Even small chips on a car body are not just a cosmetic defect. They become a source of corrosion, which over time corrodes the metal, leading to rust and costly repairs. According to car service statistics, 80% of owners of cars with more than 3 years of use are faced with this problem. But not every chip requires professional intervention: many damages can be repaired yourself, saving up to 70% of the cost of painting in a workshop.
In this article we will look at 7 ways to cover up chips - from temporary solutions to full restoration of the paintwork. You will learn which materials are suitable for different types of damage, how to properly prepare the surface and avoid mistakes that will only aggravate the problem. And for those who are afraid of ruining the body, we have prepared step-by-step instructions with photo examples and checklists.
1. How to determine the type of chip and choose a repair method
Before undertaking repairs, you need to evaluate depth and area of damage. This determines what material is required and how durable the result will be. All chips are divided into 3 categories:
- πΉ Superficial - affect only the varnish or top coat of paint. Most often they arise from small pebbles or branches. Such damage can be repaired by polishing or waxing.
- πΉ Average β penetrate to the ground or metal, but do not cause corrosion. Requires base paint and varnish.
- πΉ Deep - reach metal, often with signs of rust. Here, complete processing is already required: corrosion removal, priming, painting and varnishing.
If chipped less than 2 mm in diameter and didn't reach the metal, enough cosmetic repairs (pencils, polishes). Damage from 2 to 5 mm already require use car enamels in cans or repair kits. Chips more than 5 mm or with rust, it is better to trust the professionals - improper processing will lead to the spread of corrosion.
β οΈ Attention: If the chip is on door edge, hood or bumperWhere the metal is thinner, even minor damage can quickly rust. In such cases, it is better not to experiment with improvised means, but to use professional materials.
2. Temporary solutions: when you urgently need to disguise a chip
Sometimes you need to quickly hide a defect - for example, before selling a car or going on a trip. Suitable for this improvised means, which do not restore paintwork, but visually mask the damage:
- ποΈ Wax pencil (Turtle Wax, Sonax) - fills small chips, protects from moisture for 1-2 months. Suitable for damage up to 1 mm. Price: from 300 β½.
- π¨ Corrector-marker (Touch-Up Paint, Motip) - contains paint close to the body color. Lasts up to 6 months, but does not protect against corrosion. Cost: 400β800 β½.
- π§΄ Polish with wax (3M, Meguiarβs) - masks scratches and small chips, adds shine. The effect lasts until washing. Price: from 500 β½.
- π οΈ Invisible sticker (vinyl film) - temporarily seals the chip, protecting it from dirt. Suitable for damage up to 3mm. Costs from 200 β½ per sheet.
These methods do not replace full repairs, but they will help prevent moisture from entering the metal for 1β3 months. The main thing is not to use them on deep chips with rust: corrosion will develop faster under a temporary coating.
Before applying a wax pencil or marker, be sure to wash and degrease the surface White spirit or antisilicon. Otherwise, the product will not stick and will quickly wash off.
3. Step-by-step instructions: how to cover chips with auto enamel
If the chip has reached the ground or metal, but rust has not yet appeared, the best option is repair kit with auto enamel. We will look at the process using the example of a set Dupli-Color Scratch Fix (cost ~1,200 β½), which includes primer, paint and varnish.
What you will need:
- π§Ό Degreasing agent (White spirit, Antisilicon)
- π§½ Soft lint-free napkin
- ποΈ Brush or applicator from the set
- π Magnifier (for quality control)
- π‘οΈ Hairdryer (optional, to speed up drying)
Step by step process:
βοΈ Preparation and painting of the chip
Cleaning and degreasing. Wash the car, or at least the chipped area, with car shampoo. Dry and wipe White spirit - this will remove grease and silicones that interfere with paint adhesion.
Primer. Apply the primer from the kit in a thin layer, without going beyond the boundaries of the chip. Let dry for 10-15 minutes. If the chip is deep, repeat the procedure.
Painting. Carefully fill the chip with paint, slightly overhanging the edges. Apply 2β3 thin layers with an interval of 15 minutes. Avoid drips!
Varnishing. After the paint has dried (30β40 minutes), apply varnish. It will protect the paint from UV rays and add shine.
Polishing. After 24 hours, polish the repair area with a soft cloth and polish (3M Perfect-It).
β οΈ Attention: Do not use acetone or solvent 646 for degreasing - they will damage the factory paint around the chip. Also, do not paint at temperatures below +10Β°C: the enamel will lie unevenly.
What to do if the paint runs?
If drips appear after painting, do not breathe on them and do not wipe them with a napkin! Wait for it to dry completely (24 hours), then carefully cut off the drip. stationery knife and polish the place abrasive paste (for example, 3M Trizact).
4. Repairing Rust Chips: A Complete Guide
If corrosion has already penetrated the chip, ordinary painting will not help - the rust will continue to spread under the new layer. Needed here integrated approach:
Removing rust. Use rust converter (Tsinkar, Hi-Gear) or mechanical cleaning sandpaper P800. Important to remove all rust, even if it is barely noticeable.
Application of anti-corrosion primer. After cleaning, treat the area acid soil (Reoflex, Body 992). It creates a protective layer and improves paint adhesion.
Putty (for deep chips). If the damage is more than 1mm, apply a thin layer finishing putty (Novol, 3M) and polish sandpaper P1200.
Painting and varnishing. Next, the process is similar to the previous method: primer β paint β varnish.
To remove rust don't use:
- β Vinegar or citric acid β they corrode the metal.
- β Hard brushes - leave scratches.
- β Gasoline or kerosene - greasy stains will impair paint adhesion.
| Material | Purpose | Cost (β½) | Service life |
|---|---|---|---|
| Tsinkar | Removes rust, creates a zinc layer | 250β400 | 1β2 years |
| Kudo KV-7001 | Rust to soil converter | 300β500 | 3β5 years |
| Body 992 | Acid primer for anti-corrosion protection | 600β900 | 5+ years |
| Novol Plus 760 | Finishing putty for deep chips | 400β700 | Durable |
When working with rust, the main thing is not to rush. Even a small, unremoved source of corrosion will grow in 6 months and ruin the entire repair.
5. Professional kits vs. available means: what to choose
There are dozens of chip repair products on the market, from cheap markers to professional kits. We compared 5 popular solutions according to criteria price/quality/durability:
| Means | Type of repair | Pros | Cons | Price (β½) |
|---|---|---|---|---|
| Turtle Wax Scratch Repair | Temporary (up to 3 months) | Quickly, without skills, masks small chips | Does not protect against corrosion, washes off | 350β500 |
| Dupli-Color Scratch Fix | Semi-professional (1β2 years) | Includes primer and varnish, suitable for chips up to 3mm | Requires caution, color may not match | 1 200β1 500 |
| Chipex | Professional (3β5 years) | Exact color match, complete set with instructions | Expensive, difficult for beginners | 2 500β4 000 |
| Rust-Oleum Automotive | Anti-corrosion (2β4 years) | Fits well and is resistant to detergents | Takes a long time to dry (48 hours) | 800β1 200 |
| Nail polish + toothpick | Emergency (up to 1 month) | Cheap, always at hand | Turns yellow, cracks, does not protect the metal | 50β100 |
For long-term repair optimal sets Dupli-Color or Chipex. If needed maximum corrosion protection, choose Rust-Oleum with anti-corrosion additives. Available means (nail polish, superglue) are only suitable as a temporary measure.
β οΈ Attention: The paint color in the kits may vary slightly from the factory color of your car. For a perfect match, order tinting by VIN code at a car service (cost ~1,500 β½).
6. Typical mistakes when repairing chips and how to avoid them
Even with good materials, you can ruin the body if you donβt know the nuances. Here 5 most common mistakes and how to prevent them:
- π΄ Insufficient cleaning. If dirt or grease remains on the surface, the paint will peel off after a few months. Solution: Use 2-stage degreaser - first with a napkin, then with a clean cloth.
- π΄ The paint layer is too thick. This leads to drips and long-term drying. Solution: Apply 3 thin layers with an interval of 15 minutes.
- π΄ Ignoring the ground. Without a primer, the paint will fade and peel off faster. Solution: Always use primer, even on small chips.
- π΄ Repairs in direct sunlight. The paint dries unevenly and bubbles may appear. Solution: Work in the shade or garage at a temperature of +15...+25Β°C.
- π΄ Polishing too early. If you polish wet paint, it will become cloudy. Solution: Wait minimum 24 hours before polishing.
Another common problem is color mismatch. To avoid this, test the paint for inconspicuous area (for example, under the hood) or order tinting according to body code.
7. When is the best time to contact a car service?
Not all chips can be repaired yourself. Contact a professional if:
- π Skol more than 1 cm in diameter or with bare metal.
- π Rust has eaten through the metal deeper than 0.5 mm ("ulcers" visible).
- π The chip is on body bending (doors, arches) - it is difficult to apply paint evenly here.
- π Required full detail painting (for example, with multiple chips on the hood).
- π Car over 10 years old β old paintwork can react unpredictably to new materials.
Cost of repairing chips in the service:
- π° 1β3 chips (up to 5 mm) - 1,500β3,000 β½.
- π° Local painting of the part β 5 000β10 000 β½.
- π° Rust removal + painting β 8 000β15 000 β½.
Used in car service pneumatic spray guns and infrared dryers, which guarantees uniform coverage and durability. However, for chips up to 3 mm self-repair with a high-quality kit (for example, Chipex) will give results no worse than in the service, but 3β5 times cheaper.
FAQ: Frequently asked questions about chip repair
Is it possible to cover up chips with toothpaste?
Toothpaste doesn't fit for repairing chips. It can temporarily mask minor scratches in the varnish (like an abrasive polish), but will not protect the metal from corrosion. For chips down to metal, toothpaste is useless and even harmful - its components can accelerate oxidation.
How to choose a paint color for a chip?
There are 3 ways:
- By VIN code machines (the most accurate method). Enter the code on the paint manufacturer's website (Dupli-Color, Mobihel).
- By color code (usually located on a placard under the hood or in the glove compartment).
- Visually - in the store, compare the shade on color fan.
For a perfect match, order tinting in a car service center (cost ~1,500 β½).
How long does it take for paint to dry after repairing a chip?
Drying time depends on the type of material:
- Wax pencil - 1 hour.
- Auto enamel in a can - 24 hours (full hardening - 7 days).
- Varnish - 48 hours.
- putty β 12β24 hours (before grinding).
Do not wash your car or use auto chemicals minimum 3 days after repair.
How to cover up chips on a plastic bumper?
Plastic requires special materials:
- Primer for plastic (Body 951, APP) - improves adhesion.
- Flexible paint (Motip Flex, Dupli-Color Plastic) - does not crack when the bumper is deformed.
- Matt or glossy varnish - depending on the factory coating.
Do not use regular car enamel - it will crack in a few months!
Is it possible to paint chips in winter?
Paint at temperature below +10Β°C is not recommended. In the cold:
- The paint does not apply evenly.
- Drying time increases.
- Risk of condensation forming under the enamel layer.
If the repair is urgent, use heater or infrared lampto maintain the temperature +15β¦+20Β°C.
