How to paint a car fender on your own and with excellent results

The car wing most often suffers from careless actions of the driver. Careless parking, sharp branches, stones and other unpleasant surprises leave scratches, dents and chips on this part of the body. They not only spoil the appearance of the car, but also cause corrosion. However, you can easily fix your own work and restore the ideal smoothness of the body yourself. To do this, it is enough to know the methodology for carrying out such work and select materials of proven quality. Let's figure out how to paint a wing - quickly, efficiently and with a professional result.

Methodology for painting the wing

Preparatory work

— All work on painting a car can only be carried out in a clean indoor area - without dirt, dust and drafts. The ideal option is a spray booth. But an ordinary garage will also do, in which you first need to do a good cleaning. Do not forget that the final result of painting will depend on carefully carried out preparatory work!

— After this, the car body will need to be thoroughly washed and dried, and the area we will be working with will also need to be degreased. To do this, we use Chamäleon degreaser.

— Then we isolate the wing from the rest of the body using masking paper and Chamäleon masking tape. Thus, neighboring elements will be protected from splashes of paint and varnish during our work. After carrying out the preparatory work, we begin to study how to paint the wing, having first sanded and putty the surface.

(The stages of painting a wing are very similar to the stages of painting a bumper, so for clarity we attach our video)

Surface grinding

— The damaged surface must be treated with a coarse abrasive. To do this, take Indasa abrasive paper with a grain size of P120–P180 and begin sanding. This procedure can be carried out manually or using a grinding machine. During this stage, layers of old varnish and paint are removed, pockets of corrosion are removed, and the surface is leveled.

— After using abrasives, the surface of the wing must be thoroughly cleaned of dust. Then we treat the work area with Chamäleon degreaser. It will remove all unwanted substances from the coating, such as grease, silicone or Teflon. This will ensure optimal adhesion to the applied coatings, in addition, silicone craters will not appear during painting. How to paint a car fender if sanding alone is not enough and there are still defects on the surface?

Repairing damage

- In this case, you can’t do without putty. To do this, use a special spatula and universal ultra-light putty Chamäleon. It comes complete with a hardener and is ideal for filling cavities subject to heavy vibration. The putty is elastic and easy to sand, so no special skills are required to work with it.

— After the putty has dried, the surface is sanded using a coarse abrasive. Then you need to go over the coating with a softer abrasive with a grain size of P320–P500, paying special attention to the edges of the putty area. The surface must be perfectly flat and smooth both to the eye and to the touch.

Application of primer

Now you can start preparing the wing for painting. How to paint a wing correctly?

— First of all, the thoroughly sanded surface is treated with Chamäleon degreaser.

- Then you can start applying primer. Excellent results are obtained using standard Motip acrylic primer. It will prepare the surface for further coating with any type of paint and protect it from rust.

— It is necessary to apply 2-3 layers of primer, allowing each of them to dry for 30 minutes. The product should be sprayed from a distance of 25–30 cm to avoid smudges.

— After 2 hours, the primer will dry completely, after which the surface is sanded again using a soft abrasive P800. Now you can apply paint.

Which paint is best to choose for restoration work?

Even with careful driving and careful handling of the car, the car fender is often subject to corrosion and mechanical damage - scratches, chips.

Damage needs to be repaired

The choice of damage restoration technology depends on their size - in case of local defects, painting the entire wing is irrational due to high financial costs, here you can only get by with restoring the damaged area, whereas in case of a significant area of ​​damage you will have to remove, straighten, putty, and only then completely repaint the entire surface.

Grinding

When restoring local defects, accurate selection of paint is important, since a stain that stands out against the background of the body will not add visual appeal to the car. To do this, a table of colors is used, by comparing which with the shade of the car the required paint is selected .

Subsequent technological operations are performed according to the algorithm below:

1. Cleaning the damaged area from contamination;
2. Grinding;
3. Degreasing the surface;
4. Puttying of irregularities (if necessary in several layers);
5. Drying the putty with a hairdryer;
6. Priming the treated surface;
7. Polishing putty;
8. Wing painting.

we work with sandpaper

The technological process for restoring dimensional damage to the body is similar to the above sequence, however, painting the car is carried out in a special spray booth using a spray gun, since it is extremely difficult to paint a large surface in a high-quality manner using a homemade method.

In order to paint a car fender after restoration, it makes sense to use nitro paints specifically designed for repair work. They dry quickly (within 25 m) and upon completion of drying they are opened with a layer of varnish.

Surface painting

— When asked whether it is possible to paint the wing of a car with a spray can, experts give an affirmative answer. Motip acrylic enamel is ideal for painting the wing in this way. It has excellent performance characteristics - it is easy to apply, adheres well to the surface and forms a stable and durable coating.

— To get an excellent result, you need to choose the right paint color. This can be done using a matching catalog or a color fan. Experts can also help in this difficult task - you will need to give the serial number of the body color and, perhaps, bring its small painted part.

— Before working with aerosol paint, shake the can thoroughly for several minutes. The enamel is sprayed onto the wing from a distance of 30 cm. After applying the first developing layer, the surface is inspected and felt again. If any unevenness remains, we sand it again. It is better to apply several thin layers, allowing each to dry for 20-30 minutes.

— The final stage will be to consolidate the result using Motip acrylic varnish. Apply 2 layers, allowing each to dry. Now we know how to paint a car fender - correctly and with excellent results.

If you strictly follow painting technology and use high-quality materials, you will be satisfied with the result. A freshly painted wing will delight the eye with a radiant shine. Read our tips and get to work quickly!

Paint color selection

Even if the driver knows the original car enamel color number and manufacturer, this does not guarantee that the local painted area will match the rest of the paintwork. Over time, the paint loses its structure under the influence of UV rays. It is only possible to match the color exactly to the body tone approximately.

Another option is to go to a service station to have a computer select the color; here you can also order prepared auto enamel. Colorists note that the most difficult shades to choose for the front fender of a car are white, black and matte colors.

There are three types of auto enamel on the market, each of which has application features, disadvantages and advantages.

1. Nitroenamel. It is not recommended to paint the entire part. The paint does not provide gloss; it is necessary to paint in at least 5 layers. Suitable for painting small local areas. Selected if the main body color is matte.
2. Alkyd paint. Automotive enamel provides long-lasting shine and gloss, is resistant to gasoline, and is not subject to destruction by aggressive reagents. If the entire body element is painted, then alkyd enamel is applied in three layers. It dries for a long time, up to 36 hours, and cannot be polished.
3. Acrylic enamel. The paint contains synthetic and natural resins, thanks to which the paint dries quickly, gives a gloss, and is easy to polish. Apply in 2–4 layers, dry in 3–6 hours.

If partial painting of a used wing and a matte-colored body is necessary, then it is recommended to use nitro enamel, which, after drying, is as similar as possible to the old paintwork. If the body is bright, shiny, and has a chameleon effect, then choose acrylic paints.

Audi 80 Garage Edition › Logbook › Painting the wing with your own hands (from a spray can) - part 1

I will describe the process of painting a wing from a beginner’s perspective. I will also be glad to receive advice from specialists.

Initially I wanted to completely repaint the entire car in wet asphalt color, because... The car is 27 years old, I would like to freshen up the paint and remove small bumps on the body. But in order to do it at a lower quality, they asked for 100,000 (with materials), provided that I remove everything from the car myself (like the car is not new, something might break).

But after thinking a little, in the near future it was decided to repaint it myself, with dismantling the entire interior, shvi, processing the found corrosion (and it will happen in any case). In the meantime, find a good compressor, a good garage.

But in order not to drive with such a peeling fender, repaint them in their original color from a spray can, remove corrosion if there is any, and at the same time get a feel for it.

The most important thing in painting is preparing the base, which takes 80%, the remaining 20% ​​is painting itself.

Well, in general, everything is in order.

1. Preparation and polishing.

First, you need to clean the surface with 320-grit sandpaper, I used an orbital machine with adjustable speed, I recommend buying something that will be useful in the future on the farm, besides, the sandpaper on the machine does not clog up so quickly.

I sanded the corners and contours by hand, but for the corners it is better to use tape - Bright used red. Scotch-brite is an irreplaceable thing, in some cases it is even better than sandpaper, because... The sandpaper gets clogged very quickly. It costs 100 rubles, but it’s almost the same if you buy 4 sheets of sandpaper, but it’s more pleasant and faster to work with. By color I chose green, red and gray. I mostly worked in red in the corners.

Let me get ahead of myself, whoever is going to do the paint themselves is better off buying a professional mask right away. At first, the store recommended a disposable 3M mask, but you really start to choke in it and end up rushing to paint, which can lead to messes.

So I go over the wings with 320 sandpaper and red Scotch Brite in the corners, in some places I used green, and then rubbing it with red reduced the risk. The main task is to completely remove the varnish, where the varnish has already peeled off I rub it down to the primer, where the whole one I stop approximately in the middle of the paint.

There were chips on the wing arches in some places, I cleaned them down to metal because... Corrosion was visible, then it will be puttied. In general, I thought it would be much worse; good metal is nothing to say. Just in case, I treated it with zinc and left it overnight.

2.Priming and filling.

The materials used in the process (from left to right) were Body 960 acid primer, Jeta pro acrylic primer and Novol Alu aluminum dust putty.

It is imperative to degrease after each stage of work; for metal, I used a cheap degreaser, and where it was more responsible, a more expensive one.

After the car has been left for a day, the zinc must be washed off; I washed it with solvent 646; where it didn’t wash off, I cleaned it with sandpaper. I go over the wing first with a cheap degreaser, then with a normal one. Then I cover it with acid primer, 2 thin layers with intermediate drying for 5 minutes. The acid is where the bare metal is.

I wait about 20 minutes, the acid agent dries quickly, then I go over it with gray Scotch-Brite, slightly matting the surface. Since you can’t put putty on top of it, I degrease it and cover the wing with acrylic primer 2 layers, see photo. The second point is that this layer of soil allows you to identify all the jambs at the grinding stage.

The soil dries for a day, then I go through the places where it needs to be puttied with 240-grit sandpaper, then putty the problem areas. I used Novol Alu putty (see photo). I also updated the seam sealant on the body and decided to putty this seam. The mastic that was applied to the lower part of the body under the bumper 2 years ago has been preserved quite well.

How to paint a car fender with your own hands? Practical recommendations.

Stages of work

It is the car fender that most often undergoes minor repairs. It suffers most from minor collisions or poor parking. In this case, painting the car fender is required, which you can easily do yourself.

In fact, this is not such a difficult job and therefore you should not contact a car repair shop every time. After all, at home you can perfectly cope with this task, but you must meet a number of conditions and have all the necessary tools and materials.

Preparatory stage

It is the preparatory work that will take the most time.
But without them, it will not be possible to achieve the desired result. First of all, you will need to prepare the place where painting will take place. This is usually done in the garage. In order not to waste extra time, you should collect all the necessary materials.

You will also need a set of necessary tools for disassembly and equipment such as a compressor and a spray gun. Only after this can you begin to carry out the work directly.

Preparing and polishing the wing

Before painting, you must thoroughly wash the entire car and dry it well. It would be best to remove the front fender. True, you will have to unscrew the fender liner, headlight and bumper to do this.

To make it easier to work on the rear fender, it will be necessary to remove the door seals, feet, hatch and other components.

Then the entire car, and especially the adjacent areas with the wing, must be well covered with film, masking tape or paper. This will prevent any primer or paint from coming into contact.

The wings need to be thoroughly degreased and inspection begins. It is necessary to identify all the scratches and defects that have appeared. To do this you will need a stripping plane.

The resulting rust is removed using P120-180 sandpaper or using a converter that quickly reduces iron oxide.

While working, keep white alcohol or another solvent on hand and degrease immediately. At the same time, we must try to carry out this stage as quickly as possible.

Primer and putty

The primer will prevent further spread of rust. It dries in about half an hour, and then it is also sanded with a fine abrasive material and immediately degreased.

Automotive putty is applied using a special spatula. With its help, it is necessary to eliminate all deep and remaining minor defects.

Surface preparation

Preparation also includes several steps regarding stripping, sanding and priming. In many ways they are similar to previous operations.

One point must be taken into account. If the front fender is to be painted, it is better to put it back in place before priming. It is better not to touch the body with your hands anymore, since the painting process itself remains.

Dent Removal

But before that, you need to once again pay attention to the resulting dent or damage.

If it is small, then simply filling it with putty will be enough. If the surface is not severely damaged after the impact, then it is not necessary to remove all the old paint and primer.

If the damage is large enough, then you need to remember that many layers of putty can cause severe shrinkage over time. This is especially true for alkyd and nitrocellulose putties. The total thickness should not be more than 0.3 mm. But epoxy allows you to apply up to 2 mm. The shrinkage here is minimal.

Paint color selection

Of course, the selection of the required shade is best done in workshops or specialized services. To do this, they have the necessary equipment and experienced personnel.

Therefore, it is not enough to name the factory paint markings. Over time, it may change color slightly. A small painted part will allow you to quickly select the right paint. Even the gas tank flap is good. The main thing is that it is not plastic.

If you can find suitable canned paint in the store, that will be nice. But you can make a computer selection. True, it is not so cheap and costs on average $15 per 100 grams.

The most commonly used coating is automotive enamel. It contains not only a coloring pigment, but anti-corrosion, water-repellent and fire-resistant elements. Three types of such coating are mainly used.

Only after this do they begin the final stage.

Painting the rear fender, like the front fender, will not require much effort or time.

Material application process

If the paint is in a can, you will need a compressor and a spray gun. Although very often it is found in cans, which greatly simplifies the entire procedure.

Wing varnishing

Preparation for this stage begins already during the application of the third layer of paint on the wing.
The varnish must be mixed in advance along with the hardener and solvent. The required proportions are usually indicated on the packaging.

The process of applying varnish is similar to painting. There's just a slight difference. You don't need to use too many layers here, two will be enough.

After applying the first layer, you need to wait for it to dry for 20 minutes. Then you can apply a second layer. The main thing is to prevent leaks. Therefore, the same rules are followed as when painting.

It should be noted that the varnish can dry completely only within two days. Only after this the updated wing will be able to serve for quite a long time.

Primer and putty

Priming the metal surface prevents the occurrence and spread of corrosion; for plastic wings, a primer is used that increases the adhesion rate, due to which the car enamel lays down in an even layer and has optimal adhesion.

The putty is applied to level the surface and prepare the base for painting; it is recommended to do this with a thick rubber trowel. The composition of the putty can be one- or two-component. The two-component material must be prepared by diluting the putty with the hardener in the ratio specified by the specific manufacturer. One-component putty is more convenient because the material is ready for use immediately. Primer and putty process step by step:

1. Treat the cleaned metal wing with a rust converter.
2. Apply a thin layer of primer or primer and let dry.
3. Take a small amount of prepared putty with a trowel. Apply to the dent, level the surface, and let dry for 30 minutes.
4. Clean the putty surface and degrease. If necessary, apply a second coat of putty.

After complete drying, sand the surface with fine-grain sandpaper P -500 or higher. You can use matting paste to eliminate the transition, but drivers recommend using standard sandpaper P 600-800.

What should you consider when painting a wing yourself?

The biggest problem you can encounter when painting a wing is dust. It may not be noticeable to the naked eye, and the garage may seem clean, but when exposed to a spray gun, it rises out of nowhere, subsequently creating a sandpaper effect on the painted fender. Therefore, when painting a car fender with your own hands, you should pay special attention to cleaning the room - thoroughly vacuum and wash the floor.

We paint the new wing strictly in overalls, which should include rubberized gloves and a mask. This way you can minimize exposure to harmful substances when inhaling paint and working with solvents.

Stages of work execution

Painting work includes several stages, which must be performed strictly in the order in which they are indicated. Before you paint a car fender with your own hands, you need to properly prepare it. The surface must be perfectly clean and smooth, without any visible defects.

Before painting the wing, it is necessary to properly prepare it

It is worth not forgetting about workplace equipment. It is impossible to carry out work in poor conditions; the room must be clean and well ventilated. Dust is the main enemy of fresh paint.

Depending on the damage to the fender (scratches, dents or corrosion), the list of work may vary, but there is still one constant rule - the car must first be washed and dried. If the design of the car allows you to remove the wing, then it is easier to unscrew it and paint it separately.

A universal list of painting steps is given below.

Preparing and polishing the wing

Before restoring and painting the wing, it is necessary to carefully sand the damaged areas or the entire part as a whole.

How to grind correctly? You need to start from the places where the filler was previously applied. The abrasive wheel P80 – P180 is designed for them. Next, they move on to medium-grain sandpaper (up to P320) and treatment of the entire surface to smooth out the marks of primary sanding. At the completion stage, proceed to sanding with fine sandpaper. If necessary, stripping is carried out down to metal.

When sanding by hand, you need to apply proper pressure to the surface. Movements should be linear, not circular. Otherwise, large scratches will remain on the surface of the wing.

Sanding the wing before painting

Prime and putty the surface

After sanding, the wing must be puttied, after which the resulting smooth surface with a minimum number of open pores will be obtained. During the puttying process, the wing must also be sanded. To achieve an ideal result, more difficult areas must be sanded by hand.

You can do this as follows:

After puttying, it is necessary to apply the primer with a spray gun in 2-3 layers at a working pressure within 3-4 atmospheres. Adjust the torch so that it resembles the shape of an elongated oval. Before priming, be sure to do a test on a test surface.

Apply layers with a break of 5-10 minutes (until one layer dries). The first layer should be thin, and the second should be denser.

Leave for 24 hours, then sand the top with P500 – P600 sandpaper if the part will be painted metallic.

Puttying the wing before painting

Painting

The painting process itself is much easier than the preparatory stages. Before you start painting, you need to decide how much paint you will need. On average, it takes 150-200 g to paint one wing, if we take test paints into account.

How to paint a car fender:

Typically, drying times vary depending on the paint used. It is usually indicated on the packaging. For example, acrylic paint dries in about 10 minutes.

Varnishing

The last step in painting the wing is varnishing. The varnish is applied after all layers of paint have dried. It will turn the coating into gloss and protect the paint from rapid abrasion and fading.

The varnishing process depends entirely on the type of varnish used. In addition, weather conditions are taken into account. If varnishing is carried out in winter, the holding time increases significantly.

The process of painting a car wing will not take much time.

If the wing defect is small, then it must be painted and varnished in sections. To avoid the difference between the old coating and the fresh varnish, use a transition solvent, which is filled with a spray bottle and lightly sprayed onto the transition boundaries. This is done if the side edges of the wing are damaged. If the damage is in the center, it is recommended to do a local touch-up and completely varnish the wing, rather than fill all the edges with solvent.

After the varnish has dried, a visual inspection of the wing is carried out. If there are minor defects, the varnish is polished by machine using abrasive pastes. To avoid deviations, it is recommended to strictly follow the painting plan.

Price

Painting one entire car wing at a specialized service station costs from RUB 5,000. The work includes:

• straightening dents;
• provision of materials;
• selection of paint;
• final processing.

Do-it-yourself painting is much more profitable and simpler; difficulty arises if you need to straighten dents on a plastic fender or putty on an aluminum part. For such work, minimal experience is required, which is quite possible to obtain by doing your own repairs.

Recommendations from experts

Do-it-yourself painting of a new wing is done using a sprayer at a distance of at least 30 cm strictly perpendicular to the surface, otherwise the result may be a non-uniform shade.

If painting is done in warm weather, allow each coat of paint to dry for at least 20 minutes before applying another. As a rule, the manufacturer writes detailed instructions for the paint, which you must read before starting work.

Each layer of paint should lie extremely evenly, without smudges. Gaps are allowed only when applying the first layer.

According to the recommendations of experts, to obtain an ideal result after finishing the fender painting work, it is recommended to polish the entire car. This way, the car will look like new, and the freshly painted wing will not be conspicuous by its shine.

Preliminary work on a damaged wing

Next, the following stages of preparatory work are carried out:

Necessary tools for painting the wing

1. Sanding damage:

• if there are only light scratches on the surface, then it is enough to achieve a matte finish;
• if the layer is damaged down to the metal, then there is a risk of rust formation, so the area needs to be thoroughly cleaned with sandpaper P120-180, and then used to combat corrosion.

Degreasing the work area. To do this, you can use white spirit or even acetone, and after the applied product has dried, immediately prime the surface

Here it is important to do everything as quickly as possible, so you will avoid the risk of the smallest particles of rust. Grinding the primed area with a fine abrasive, removing dust and re-degreasing

Please note that the surface must be completely smooth. If there was serious damage to the surface, then they need to be puttied and sanded until the geometry is completely restored. To do this, use an abrasive of 320-400 grit and only the dry processing method. If you still have a feeling of roughness, then use paper with P500. Next, you need to matte all adjacent areas of the wing with your own hands by removing paint and varnish around the damaged area. Here you need to use matting paste or paper with P1000-1200. This must be done so that the transition from new paint to old is least noticeable. Sanding the surface for future painting. You need to work with small areas, gradually increasing their size. Then the entire painting area is primed. It is necessarily preceded by high-quality degreasing. The application of the primer should be carried out in parallel lines, each subsequent one should slightly touch the previous one and slightly extend beyond the putty areas. Here, pay close attention to the instructions on the primer can - these recommendations take priority. After drying, the primer is sanded with a fine abrasive and degreased. After this, you should walk over the surface with a special sticky cloth, which will collect any remaining dust. Touching the surface with your hands is strictly prohibited!

Cost of painting a wing at a car service center

The most popular choice is two types of paint - acrylic enamel and metallic. In the first case, purchasing consumables costs around 2000 rubles, and in the second – 2400-3000 rubles.

If you resort to the services of a car service, then painting a car wing costs 2000-2500 rubles. more expensive if you add this cost to the main consumables. This is the case if the damage is not serious. In other cases, painting the wing will cost a tidy sum (about 10,000 rubles). If you've ever had to deal with car repairs and have your hands in the right place, then painting your car fender yourself will significantly save your budget.
