Chips on the paintwork of a car are a problem that every owner faces, regardless of how careful they are when driving. Pebbles from the road, branches, bad parking, or even bird droppings can leave marks on the body that eventually lead to corrosion. According to research 3M and PPG, more than 60% of body damage begins with chips, which owners ignore at an early stage.
Many people believe that minor defects do not require urgent intervention, but this is a dangerous misconception. Even a microcrack in the paint allows moisture and salt access to the metal, starting the rusting process. In this article we will analyze all stages of chip removal - from diagnostics to professional repair methods, and we will also tell you which materials to choose for different types of damage and how to avoid common mistakes.
You will learn:
- 🔍 How to correctly assess the depth of a chip and determine whether a specialist’s help is needed
- 🎨 What materials (from pencils for touching up up to two-component enamels) suitable for self-repair
- ⚠️ Why can't be ignored chips on aluminum bodies (for example, Audi A8 or Jaguar XF)
- 💰 Cost of repairs in service vs. self-removal: which is more profitable
1. Diagnosis of a chip: how to determine the degree of damage
Before undertaking repairs, it is necessary to accurately assess how deep the damage is. The choice of restoration method and materials depends on this. Chips are classified according to three levels:
- Superficial - affect only the varnish or top coat of paint. Visually they look like white or matte dots.
- Average — the varnish and paint are damaged, but the primer remains intact. The color of the metal or primer is often visible.
- Deep — the chip reaches metal or plastic (on bumpers). The most dangerous, as they lead to corrosion.
For diagnosis you will need:
- 🔦 Flashlight or magnifying glass with backlight (for example, Xiaomi Mi LED Desk Lamp)
- 🧲 Magnet (to check the presence of putty at the chip site)
- 📏 Ruler or caliper (for measuring depths greater than 0.5 mm)
Critical point: if the chip is on the edge of the door, hood or wings (high load area), it must be eliminated first - here corrosion spreads 2-3 times faster.
2. Repair materials: what to choose for different types of chips
The auto chemical goods market offers dozens of solutions - from budget corrector pencils to professional painting kits. Let's figure out what is suitable for each case.
| Chip type | Recommended Material | Approximate price (2026) | Difficulty of application |
|---|---|---|---|
| Surface (varnish) | Polish with abrasive (Meguiar’s Ultimate Compound) | 800–1 500 ₽ | ⭐ |
| Medium (paint) | Touch-up pencil (Dr. ColorChip) or set Touch-Up Paint | 1 200–2 500 ₽ | ⭐⭐ |
| Deep (to metal) | Primer + paint + varnish (PPG Deltron, Sikkens Autowave) | 3 000–6 000 ₽ | ⭐⭐⭐ |
| Chip on plastic (bumper) | Special paint for plastic (MOTIP Dupli-Color) | 1 500–2 800 ₽ | ⭐⭐ |
To select the exact paint color, use Vehicle VIN code or contact your dealer. For example, for Toyota Camry For 2020, the color code is indicated in the service book or on a plate under the hood. If you choose a shade yourself, the risk of mismatch is up to 30%!
⚠️ Attention: Do not use nitrocellulose-based automotive clearcoats (such as Nitro Lack) for repairing modern cars - they are incompatible with water-soluble paints used to cover bodies after 2015.
3. Step-by-step instructions: how to fix a chip yourself
Let's consider a universal algorithm for chips of medium depth (to the ground). To work you will need:
- 🧴 Degreaser (APP Wash & Wipe)
- 🖌️ Brush or applicator (included with paint)
- 🧪 Primer in a can (Body 992)
- 🎨 Paint (selected by code)
- 💎 Varnish (Spies Hecker Permahyd)
- 🧼 Polishing paste (3M Perfect-It)
☑️ Preparation for chip repair
Step 1: Cleaning and Preparation
Remove wax, silicone polishes and dirt from the surface using degreaser. Wipe the chip with a lint-free cloth. If there are rust particles left inside, use rust converter (ASTROhim Antiruster).
Step 2: Primer
Apply a thin layer of primer using a brush or spray can (keep at a distance of 15–20 cm). Let dry for 10-15 minutes. To speed up drying, use infrared lamp, but not a hair dryer - it creates turbulent air currents that raise dust.
Step 3. Painting
Apply paint in 2-3 layers at intervals of 5-7 minutes. Each layer should be thinner than the previous one. Convenient to use for spot chips micro brush or airbrush (for example, Harder & Steenbeck Infinity).
If the paint is too thick, thin it base thinner (no more than 10% of volume). For metallics and pearls, be sure to use hardener - otherwise the color will be dull.
Step 4: Varnishing and polishing
After the paint has dried (24 hours), apply varnish. After a day, polish the surface abrasive paste (3000-5000 grit) and finish protective polish (Collinite 845).
⚠️ Attention: If the chip is on a vertical surface (for example, on a door), apply paint from bottom to top to avoid drips. For horizontal surfaces (hood, roof), use the “wet on wet” method - each subsequent layer is applied before the previous one dries.
4. Features of repairing chips on different types of bodies
The body material dictates the specifics of the repair. Let's look at the key nuances for the most common types.
🚗 Steel bodies (most mass models)
The most repairable, but susceptible to corrosion. The main task is insulate metal from moisture. For deep chips, be sure to use epoxy primer (U-Pol Acid #8), which creates a chemical bond with the metal.
🛡️ Aluminum bodies (Audi, , )
Aluminum oxidizes 5 times faster than steel when in contact with water, so chipping is critical here. For repairs, use special primers for non-ferrous metals (PPG DP40LF) and avoid abrasive polishing - it destroys the protective oxide layer.
🔳 Plastic bumpers
Plastic does not rust, but paint does not adhere to it well. Be sure to apply before painting adhesive primer (3M Scotch-Weld). For flexible bumpers (e.g. on Renault Duster) use elastic paints (MOTIP Flexible Bumper Paint).
💎 Carbon parts (BMW M-series, Lamborghini)
Carbon requires a special approach: it cannot be sanded with sandpaper (the structure of the fibers is destroyed). For repair use epoxy resins with pigments matched to the color of the part. It is better to entrust the process to professionals - a mistake will lead to delamination of the material.
Why can't you use regular putty on aluminum bodies?
Conventional polyester putty contains iron powder, which reacts galvanically with aluminum, accelerating corrosion. For Audi or
5. Typical mistakes when repairing chips and how to avoid them
Even experienced car owners make mistakes that ruin all their efforts. Here are the most common:
- 🌡️ Low Temperature Repair (below +10°C) - the paint applies unevenly and the varnish becomes cloudy. Use heater or move the work to a warm room.
- 🕒 Failure to adhere to drying time - if you apply varnish to wet paint, bubbles will appear. For acrylic paints, the minimum drying time is 6 hours.
- 🧴 Using household nail polish - it turns yellow after 2-3 months and does not protect against UV rays. Only car varnishes (Spies Hecker, Sikkens).
- 🔧 Sanding without water — dry sanding leads to microcracks in the paint. Always use
wet sanding(sandpaper + water).
Another common problem is color mismatch. Even if you selected paint by VIN code, the shade may differ due to:
- Burnout of original paint in the sun
- Different types of varnish (matte/glossy)
- Applying paint too thickly
If the color is different after repair, try polishing the transition between the old and new paint abrasive paste with grit 1000–1500. This will smooth out the border and visually even out the shade.
6. When to contact service: signs of complex damage
Not all chips can be fixed on your own. Contact a professional if:
- 🔍 A chip greater than 5 mm in diameter or more than 0.3 mm deep
- 🛠️ The damage is on body bend (for example, on the door line)
- 🎨 Required paint transition (shading over a larger area)
- ⚡ There are signs of corrosion (red spots, blistering paint)
- 🔧 Needs restoration part geometry (dent + chip)
The cost of repairs in the service depends on the complexity:
| Type of work | Price (2026, Moscow) | Lead time |
|---|---|---|
| Local painting of chips (up to 3 cm) | 2 000–4 000 ₽ | 1–2 days |
| Repairing a chip with corrosion | 5 000–8 000 ₽ | 2–3 days |
| Complete painting of an element (door, wing) | 15 000–30 000 ₽ | 3–5 days |
To save money, you can combine methods: for example, prime and paint the chip yourself, and entrust polishing and varnishing to a master.
⚠️ Attention: If your car is under warranty, repairing chips yourself may result in denial of warranty service for the body. Please check with your dealer before starting work.
7. Prevention of chips: how to protect the body from damage
The best repair is prevention. Here are effective ways to protect yourself:
- 🛡️ "Liquid glass" or ceramic coating (Ceramic Pro, Gyeon Ceramic Coating) - creates a protective layer 2–5 microns thick that can withstand impacts from small stones.
- 🎨 Anti-gravel film (3M Scotchgard, XPEL) - transparent polyurethane film for vulnerable areas (hood, bumper, sills).
- 🚘 Armored glass for headlights — prevents chipping from stones that often hit the optics.
- 🧴 Wax or synthetic protective polishes (Collinite 476S, Poorboys World) - reduce the adhesion of dirt to paintwork.
For added winter protection, use anti-corrosion mastics on the thresholds and arches (Dinitrol 4941, Tectyl). Apply them in the fall, before the first frost.
If you often drive on gravel, install hood deflectors (Hepco or Rally Armor). They deflect the flow of stones and reduce the risk of chipping by 40–60%.
FAQ: Frequently asked questions about repairing chips
Can I paint over a chip with nail polish?
No, this is a temporary solution that will lead to even bigger problems. Nail polish is not resistant to UV rays, temperature changes and detergents. After 1-2 months it will turn yellow and begin to peel off, and corrosion may appear underneath. Use only automotive clear coats.
How to remove a chip if the paint has already begun to rust?
Remove the rust first converter (Tsinkar, WD-40 Specialist), then sand the area with sandpaper (P800–P1000). After degreasing, apply acid soil (Reoflex Acid Primer), which neutralizes corrosion residues. Only then paint and varnish.
How long does it take to repair a chip done yourself?
With the correct selection of materials and technology - from 2 to 5 years. The period depends on:
- Paint quality (professional lines PPG or Sikkens last longer than budget ones)
- Operating conditions (winter driving on roads treated with reagents shortens the service life)
- Availability of additional protection (ceramics, anti-gravel film)
For comparison: service repairs with a warranty last 5–7 years.
What is the difference between repairing a chip on a new car and on a car older than 10 years?
On older cars (before 2010) it is often used acrylic enamel, which fades over time. When choosing paint, keep this in mind - the original color may have changed by 1-2 tones. Also more common on older bodies hidden corrosion, so be sure to check the metal with a thickness gauge before painting.
On new cars (after 2015) they use water-soluble paints, which require special thinners. Also, modern paintwork is thinner (100–120 microns versus 150–180 microns on older cars), so you need to sand them more carefully.
Is it possible to paint over a chip without polishing?
It is possible, but the result will be noticeable. Without polishing, the border between the old and new paint will remain visible, and the varnish will lie unevenly. If the chip is small (up to 1 mm), you can do without polishing, but for an aesthetic result it is better to polish the repair area.
