Touching up chips on a car body: a complete guide from A to Z

Chips on a car body are not only an aesthetic problem, but also a potential threat of corrosion. Even a small defect in the paintwork can turn into a rusty stain over time if action is not taken promptly. Many car owners put off repairs, considering them difficult or expensive, but in fact touch up chips on a car you can do it yourself, saving on car service costs.

In this article we will figure out how to choose the right paint, prepare the surface and apply the coating so that the result is as invisible as possible. You will learn about the professional secrets that painters use and avoid typical beginner mistakes. We will also tell you in which cases it is better not to take risks and turn to specialists.

Chips occur due to small stones, gravel, branches or careless parking. The longer you delay repairs, the higher the risk that moisture will penetrate under the paint and begin to oxidize the metal. But don’t rush to panic: modern tools allow you to eliminate defects even without experience. The main thing is to follow the technology and not skip the preparation stages.

If you've never done body repair before, start with inconspicuous areas, such as the bumper or sills. This will help you get your bearings before working on visible parts of the car. And to ensure that the result lasts a long time, we will analyze each step in detail - from diagnosing the damage to final polishing.

1. Damage assessment: when you can paint yourself and when you can’t

Not all chips are the same. It depends on their depth and area whether you can handle it yourself or have to go to a car service center. Surface chips (when only the varnish or top layer of paint is damaged) can be easily fixed at home. But deep chips to metal require a more serious approach - sometimes even welding or putty.

Here are the key criteria by which to evaluate a defect:

• 🔍 Depth: If bare metal is visible, anti-corrosion treatment and primer will be needed.
• 📏 Size: chips with a diameter of more than 5 mm are best left to professionals - self-touching may be noticeable.
• 🚗 Location: On the hood or roof, defects are more difficult to disguise due to direct sunlight.
• ⏳ Lifetime: old chips with signs of rust require pre-cleaning and treatment with a converter.

If the chip is fresh, not rusty and not deeper than the soil layer, you can handle it without problems. Otherwise, you risk making the problem worse. For example, incorrectly applied putty can peel off after a few months, and poorly primed metal will begin to rust under the paint.

⚠️ Attention: If the chip is on a body edge (such as the edge of a door or fender), doing the repair yourself may result in an uneven coat of paint. In such cases it is better to use airbrush or contact service.

For an accurate diagnosis, take a magnifying glass or flashlight and carefully examine the damage from different angles. If you see black dots or a red coating, these are the first signs of corrosion. In this case, before painting, be sure to use rust converter (for example, Tsinkar or Hi-Gear).

2. Selection of paint: color code, types and where to buy

One of the most important stages is the correct selection of paint. Even a perfectly applied coating will be noticeable if the shade does not match. Each car has a unique color code, which is indicated in the technical documentation or on a special plate (usually located on the door pillar, under the hood or in the trunk).

Where to look for the color code:

• 📄 B vehicle passport (PTS) or service book.
• 🚪 On a sticker on the driver's door pillar (often indicated as Color Code, Paint Code or just letters/numbers).
• 🔍 In electronic databases by VIN code (for example, on websites AutoData or PaintScratch).

When the code is found, all that remains is to select the type of paint. To touch up chips, they usually use:

1. Spray paint - convenient for large areas, but requires care.
2. Paint in small bottles with a brush (for example, Touch-Up Paint) - ideal for spot repairs.
3. Touch-up pencil (for example, Fix It Pro) - quick and easy, but only suitable for small chips.
4. Airbrush - a professional tool for an ideal result, but it requires skills.

Where to buy paint:

• 🏬 Official dealers - guaranteed original color, but expensive.
• 🛒 Auto stores (for example, AutoSpetsCenter, IXORA) - wide range, can be selected by code.
• 🌍 Online (for example, PaintScratch, Autopaint.ru) - convenient if you need rare paint.

⚠️ Attention: If your car is older than 5 years, keep in mind that the paint may have faded in the sun. In this case, take a shade one tone lighter or use blender (thinner for a smooth color transition).

Before purchasing, check that the kit includes varnish — it adds shine and protects the paint. Some manufacturers sell it separately. Also useful degreaser (for example, App Cleaner) and primer (if the chip is deep).

3. Surface preparation: the key to long-lasting results

Even the most expensive paint will not lie smoothly if the surface is not prepared. Many people skip this stage, but in vain - it determines how long the repair will last. Main task - clean the chip from dirt, grease and rust, and also create conditions for good adhesion (adhesion) of the paint to the body.

Step-by-step preparation:

1. Washing: Wash the car thoroughly, paying special attention to the area around the chip. Use car shampoo (eg Karcher) to remove wax and silicones.
2. Drying: Wipe the surface with microfiber and let dry naturally or use a hair dryer.
3. Cleaning the chip: If there is rust, treat it converter (for example, Permatex), then rinse with water.
4. Degreasing: Wipe the area white spirit or a special degreaser. Do not use acetone - it can damage the varnish!
5. Protection all around: paste masking tape and paper so as not to stain adjacent areas.

If the chip is deep (down to the metal), apply a thin layer before painting primers. It protects against corrosion and improves paint adhesion. For aluminum parts (e.g. hood), use a special primer, e.g. Body 992.

For convenience, you can use abrasive sponge (granularity P2000-P3000) to lightly matte the edges of the chip. This will help the paint go on smoother. But don’t overdo it—light movements without pressure are enough.

4. Paint application technique: from theory to practice

Now we move on to the most important stage - painting. The important thing here is to take your time and apply the paint in thin layers. If you overdo it, you will get sagging that will be difficult to remove. First, practice on an unnecessary part or piece of metal.

Tools you will need:

• 🎨 Brush (if you use a bottle of paint) or airbrush.
• 🔧 Toothpick or thin stick for spot touch-up.
• 💡 Lamp or flashlight for good lighting.
• 🧴 Varnish for final coating.

Step-by-step application instructions:

1. First layer: Apply paint in dots, slightly extending beyond the edges of the chip. Use a toothpick if the brush is too wide. Let dry for 10-15 minutes.
2. Second layer: repeat application, but with a small margin. The paint should slightly overlap the first layer.
3. Third layer (if necessary): If the chip is still visible, apply another coat. But don't overdo it - a thick layer of paint will be noticeable.
4. Varnishing: After the paint has dried (usually 1-2 hours), apply varnish. It will add shine and protect the coating.

If you use spray can, keep him at a distance 20-30 cm away from the surface and apply the paint in short sprays. For airbrush optimal pressure - 1.5-2 atm, and the distance is 10-15 cm.

After painting, let the car dry in a warm, dust-free place. Drying time depends on the type of paint:

• 🕒 Acrylic paint: 2-4 hours before hardening, complete polymerization - 24 hours.
• 🕒 Alkyd paint: 6-8 hours before hardening, complete drying - 48 hours.
• 🕒 Touch-up pencil: 1-2 hours.

⚠️ Attention: Do not dry paint in direct sunlight or with a hair dryer - this may cause bubbles or cracks. Optimal temperature for drying: +20…+25°C.

If the chip is on a plastic part (bumper, molding), first apply a special primer for plastic (for example, Plastic Primer). Without it, the paint may peel off after a few months.

5. Polishing and finishing

After the paint has completely dried, the final touch remains - polishing. It is needed to remove minor irregularities, make the color transition smooth and restore shine. Without polishing, the painted area may stand out from the rest of the body.

What you will need for polishing:

• 🧴 Abrasive paste (for example, 3M Rubbing Compound for rough polishing).
• 🧴 Polish without abrasive (for example, Turtle Wax for final shine).
• 🔴 Polishing machine (or a soft rag if working by hand).
• 🛡️ Protective coating (wax or ceramic for durability).

Step by step process:

1. Rough polishing: Apply abrasive paste to the polishing wheel and work on the painted area. Movements should be circular, without strong pressure.
2. Cleaning: Remove any remaining paste with microfiber.
3. Final polishing: Use a non-abrasive polish to add shine.
4. Protection: Apply wax or ceramic coating to protect against UV rays and moisture.

If after polishing the touched-up area is still noticeable, you can use paint blender - a special solvent that makes the color transition smoother. It is applied along the edges of the chip with a brush or swab.

To check the result, inspect the car in bright daylight or under a lamp. If you notice any unevenness, polish again. Sometimes it takes 2-3 approaches to achieve the perfect result.

6. Common mistakes and how to avoid them

Even experienced car owners sometimes make mistakes when touching up chips. We have collected the most common mistakes and will tell you how to prevent them.

Error	Consequences	How to avoid
Applying paint to a dirty surface	Poor adhesion, paint peeling off after a few months	Thoroughly clean and degrease the chip before painting
Using paint that is too thick	Sagging, uneven surface	Thin the paint with a solvent (if the instructions allow it)
Low temperature painting	The paint does not dry well and may crack.	Work in a warm room (+18…+25°C)
No varnish	The paint will quickly fade and lose its shine.	Always apply varnish after the paint has dried
Polishing until paint is completely dry	The appearance of scratches and chips on fresh paint	Wait at least 24 hours before polishing

Another common mistake is using the wrong tools. For example, some people try to paint chips with cotton swabs, but they leave lint. Better to use synthetic brushes or airbrush.

If there are stains left after painting, do not try to remove them immediately. Let the paint dry completely and then buff gently. Sometimes applying an additional layer of varnish helps.

And remember: if the chip is in a visible place (for example, on the roof or hood), and you are not confident in your abilities, it is better to entrust the work to professionals. Poor-quality touch-up can reduce the selling price of a car by 5-15%, especially if the defect is visible to the naked eye.

7. Care after repair: how to prolong the result

Touching up chips is only half the battle. In order for the result to last for a long time, you need to properly care for the repaired area. Here are some tips to help avoid repeated damage:

Rules of care:

• 🚿 Washing: for the first 2 weeks after painting, wash the car only by hand, without automatic car washes with brushes.
• 🌞 Sun protection: Try to park in the shade to prevent the paint from fading.
• 🧴 Waxing: Apply protective wax or ceramic coating every 3-6 months.
• 🚗 Careful driving: Avoid gravel and following closely behind trucks (they often throw rocks).

If you notice that the paint has begun to peel or new chips have appeared, do not delay repairs. The faster you fix the defect, the lower the risk of corrosion.

For additional protection you can use anti-gravel film or liquid glass. They create a transparent protective layer that prevents new chips from occurring. This is especially true for hoods and front bumpers.

What to do if the paint starts to bubble?

If bubbles appear after painting, this means that moisture got under the paint or the surface was poorly degreased. In this case, you need to completely remove the paint (for example, using washes), dry and repeat the process from the very beginning. Don't try to simply paint over the bubbles - this will only make the problem worse.

FAQ: Answers to frequently asked questions

Is it possible to touch up chips in winter?

Technically possible, but not recommended. At temperatures below +10°C the paint does not dry well and may lie unevenly or crack. If you urgently need to fix a defect, use quick drying paint (for example, SprayMax 2K) and work in a heated garage.

How much does it cost to professionally touch up chips?

The cost depends on the size of the defect and the region. On average:

• Small chips (up to 5 mm) - from 500 to 1500 rub. per piece.
• Large chips (more than 1 cm) - from 2000 to 5000 rub..
• Complete repainting of an element (for example, a bumper) - from 10,000 rub..

What is the difference between paint in a can and paint in a bottle?

Paint in spray can Suitable for large areas, but requires spraying skills. Paint in bottle with brush Applies more accurately, but is only suitable for small chips. For beginners, it is better to start with a bottle, as the can can leave smudges.

Is it possible to paint chips on a metallic car?

Yes, but it's more difficult than with regular paint. Metallic contains aluminum particles that need to be evenly distributed. To do this:

1. Apply a base coat of paint.
2. Let dry for 10-15 minutes.
3. Apply a second coat with slight overlap.
4. Apply varnish in 2 layers.

Without varnish, metallic will look dull.

How to remove smudges after painting?

If the paint runs, wait until it dries completely (24-48 hours), then carefully polish the area with an abrasive paste (P1500-P2000). If the leak is large, you may have to repaint the area again.
