Why chips on a car are not just an aesthetic problem
Chips on a car's paintwork can occur even among the most careful drivers. Pebbles from under the wheels of vehicles in front, tree branches, bad parking - and now damage is noticeable on the hood or bumper. Many car owners mistakenly believe that minor defects do not require urgent repairs. However even microscopic chips can lead to metal corrosion, if they are not eliminated in time.
In this article we will analyze all current methods for removing chips - from budget methods for do-it-yourself repairs to professional technologies in car services. You will learn what materials are needed for each type of damage, how to avoid mistakes when restoring paintwork, and when you canβt do without the help of specialists. We will pay special attention chipping to metal - the most dangerous in terms of rust, since they are the ones that require immediate action.
Before starting repairs, it is important to correctly assess the depth of the damage. To do this, a visual inspection in good lighting is sufficient. If the chip only affected the top layer of varnish, the task is simplified. But if bare metal or primer is visible, a more serious approach will be required.
How to determine the type of chip: diagnostics before repair
The choice of recovery method depends on correct diagnosis. All chips can be divided into three categories in depth:
- πΉ Superficial - affect only the varnish or top coat of paint. Most often they appear from small pebbles or sand. Visually they look like white dots or light scratches.
- πΉ Average β damage the paint down to the primer layer. Usually they have a darker shade than the main paintwork, since the primer is often gray or black.
- πΉ Deep - reach the metal. The most dangerous, since without protection oxidation begins. Such chips require immediate treatment.
For an accurate diagnosis, take a magnifying glass and a flashlight. Point the light at an angle - this will help you see the boundaries of the damage. If the chip is on a vertical surface (for example, a door), pay attention to the lower edge: dirt and moisture often accumulate there, accelerating corrosion.
Another important point - localization of defects. Chips on the hood or roof most often appear from road stones, and on the doors - from careless opening of neighboring cars. The bumper suffers from high curbs and back-to-back parking. The choice of repair method also depends on the location: for example, vertical surfaces are more difficult to polish due to flowing materials.
β οΈ Attention: If the chip is located on a fold of the body panel (for example, on the hood line), do not use abrasive polishing pastes. In these areas, the paint coating is thinner, and you can accidentally rub it down to the ground.
Budget-friendly ways to eliminate small chips (up to 500 β½)
If the damage is shallow and there are few of them, you can get by with minimal costs. Here three proven methodsthat do not require special skills:
1. Polishing with abrasive pastes
Suitable for chips that have not reached the ground. You will need:
- π§΄ Polishing paste (for example, 3M Perfect-It or Meguiarβs Ultimate Compound)
- π’ Polishing sponge or drill wheel (yellow or orange for medium abrasiveness)
- π§Ή Microfiber cloths
- π§ Car shampoo for degreasing
Procedure:
- Wash and dry the affected area.
- Apply a small amount of paste to the sponge and polish the chip in a circular motion for 1-2 minutes.
- Wipe the surface with microfiber and evaluate the result. Repeat if necessary.
- Apply protective wax or ceramic coating to seal the effect.
βοΈ What you need to polish chips
This method removes a thin layer of varnish around the chip, smoothing out the surface. However, he does not restore paint, but only masks the defect. For deep damage, polishing is not suitable - it will only worsen the problem.
2. Pencils and correctors for chips
Special coloring pencils (for example, Fix It Pro or Dr. ColorChip) contain pigment that matches the color of your car. They fill the damage and protect the metal from corrosion. Advantages of the method:
- β Fast - takes 5-10 minutes
- β Low price - from 300 to 800 β½
- β Does not require special skills
Cons:
- β Visible upon close examination
- β Short-lived - requires reapplication every 6-12 months
Tip: Before purchasing a pencil, check your car's color code (usually located on a sign in the doorway or under the hood). Manufacturers often indicate compatibility with popular shades (for example, Bianco White or Black Pearl).
3. Application of βliquid glassβ or ceramics
If the chip is small, but you want to reliably protect this place from further damage, use ceramic coatings (for example, Ceramic Pro or Gyeon Ceramic Coating). They create a durable layer 2β5 microns thick, which:
- π‘οΈ Prevents oxidation
- π Adds shine
- πΏ Makes cleaning easier
For application:
- Clean and degrease the surface with alcohol.
- Apply the composition with an applicator in a thin layer.
- Let dry for 24 hours (do not wash your car during this time!).
β οΈ Attention: Ceramic does not restore paint, but only protects the existing coating. If the chip is deep, first fill it with corrector and then apply ceramics.
Professional methods: when you canβt do without a car service
If the chips are numerous, deep, or located in visible places (for example, on the roof or hood), it is better to contact a specialist. In car services they use three main technologies:
| Method | Cost (from) | Repair time | When to use |
|---|---|---|---|
| Local painting | 1 500 β½ | 2β4 hours | Chips up to 3 cm, not on panel folds |
| Complete repainting of the element | 5 000 β½ | 1β2 days | Multiple chips on one part |
| Paintless repair (PDR) | 2 000 β½ | 1β3 hours | Chips without damage to paintwork (only dents) |
| Application of protective film | 3 000 β½ | 3β5 hours | Prevention of new chips in vulnerable areas |
The most popular method is local painting. The technician sands the damaged area, applies primer, paint and varnish, and then polishes the transition. Modern spray guns with minimal spray allow for perfect color matching. For precise selection of shade use spectrophotometers, which analyze the original paintwork.
If there are too many chips (for example, after hail damage), it will be cheaper to completely repaint the element. This is also true for cars older than 10 years, where the varnish has already lost its properties and requires updating.
To protect against future chips, many car owners cover vulnerable areas. transparent armor film (for example, 3M Scotchgard or XPEL). It withstands impacts from stones and prevents the appearance of new defects. The cost of wrapping a hood starts from RUB 8,000, but this is an investment for 5β7 years.
What is PDR technology?
This is a method of removing dents without painting (Paintless Dent Repair). A specialist uses special tools to straighten the metal from the inside, preserving the original paintwork. Suitable only for chips without damage to the paint, such as from hail or light impacts.
Step-by-step instructions: how to remove a chip to metal with your own hands
If you decide to repair a deep chip yourself, follow these instructions. You will need:
- π§ Sandpaper
P800,P1200,P2000 - π¨ Primer in a can (for example, Body 992)
- ποΈ Paint to match the color of the car (see the code on the plate)
- π Two-component acrylic varnish
- π§΄ Polishing paste
- π οΈ Masking tape and film to protect adjacent areas
Step 1. Surface preparation
Wash thoroughly and degrease the chip white spirit or antisilicon. If there is rust, remove it with a converter (eg Tsinkar). Then sand the edges of the chip with sandpaper. P800to remove burrs.
Step 2: Priming
Apply a thin layer of primer from a can from a distance of 20β25 cm. Let dry for 15β20 minutes and sand P1200 until smooth. Repeat the process 2-3 times to be sure.
Step 3. Painting
Shake the paint can for 2-3 minutes and apply the first coat. Keep the can at a distance of 25β30 cm to avoid drips. After 10 minutes, apply a second coat. May require 3-4 coats for perfect color.
Step 4. Varnishing
After the paint has dried (1-2 hours), apply the varnish in the same way. Apply varnish overlapping 3-5 cm around the chip to blend out the transition.
Step 5: Polishing
After 24 hours, polish the repaired area with abrasive paste P2000and then with protective wax.
If you have no experience working with spray cans, practice on an unnecessary part or piece of metal. The optimal temperature for painting is 20β25Β°C with a humidity not exceeding 60%.
β οΈ Attention: Do not use nitrocellulose-based car varnishes for local repairs - they turn yellow over time and do not combine well with modern acrylic paints. Give preference to two-component varnishes (for example, Mobihel 2K).
The dangers of unrepaired chips: consequences for the body
Many car owners put off repairing chips βuntil laterβ, not knowing what processes are starting in the damaged area:
- π₯ Metal corrosion β already 2β3 weeks after the chip appears, oxidation begins to reach the metal. Moisture and salt (in winter) speed up the process by 5β10 times.
- π¨ Peeling of paintwork β if the chip is on the edge of the panel, moisture penetrates under the varnish, causing it to swell and peel.
- πΈ Reducing the cost of a car β when selling, each unrepaired chip reduces the price by 1,000β3,000 β½ (depending on the model).
- π Warranty issues - some dealers refuse warranty repairs to the body if they see advanced chips.
Chips rust especially quickly on:
- π Wheel arches - due to the constant ingress of dirt and reagents.
- πͺ Bottom of doors β moisture accumulates here after rain.
- π Rapids - they are closest to the road and are subject to sandblasting wear.
Interesting fact: chips on aluminum bodies (for example, at Jaguar or Audi A8) oxidize differently than on steel. Aluminum becomes covered with a white coating, which is less noticeable, but also destroys the metal. For such machines, special primers with zinc are used.
Even one unrepaired chip down to the metal can turn into a through hole in the body in 6 months if the car is used in winter. The cost of repairs in this case will increase 10β20 times.
Chip prevention: how to protect your car from new damage
It is impossible to completely avoid chips, but you can significantly reduce their number. Here 7 ways that work:
- π‘οΈ Protective films β covering the hood, bumper and roof with transparent armored film (3M, XPEL) reduces the risk of chipping by 90%. Cost: from 5,000 β½ per hood.
- π§² Magnetic deflectors β are installed on the hood and deflect the oncoming flow of stones. Suitable for intercity travel. Price: 1,500β3,000 RUR.
- π Distance on the track β stay 50+ meters away from trucks and cars with open trunks. Stones from under the wheels fly at speeds of up to 120 km/h!
- π ΏοΈ Parking back to the road - this way the bumper and hood suffer less from passing cars.
- π§Ό Regular washing β Dirt and salt eat away at chips, accelerating corrosion. Wash your car once every 1β2 weeks (weekly in winter).
- π οΈ Anti-gravel coating - special formulations (for example, Turtle Wax Anti-Chip) are applied to vulnerable areas and create an elastic protective layer.
- π³ Avoid parking under trees β falling branches and cones often cause chips on the roof.
If you frequently drive on gravel or crushed stone, consider installing plastic protection for headlights and radiator grille. They cost 2,000β4,000 rubles, but they prevent damage that would cost many times more.
For new cars, some dealers offer anti-gravel body treatment as part of pre-sale preparation. This is a coating based on polyurethane resins, which is applied to the bottom of doors, thresholds and arches. Cost: 3,000β6,000 β½, service life: 2β3 years.
FAQ: Frequently asked questions about chip repair
Is it possible to remove chips without painting?
Yes, but only if the damage has not reached the ground or metal. In this case, polishing with abrasive pastes (for example, 3M Rubbing Compound). For chips down to the metal, you canβt do without painting - otherwise corrosion will begin.
How much does it cost to repair chips at a car repair shop?
The cost depends on the method:
- Local painting of 1β2 chips: 1,500β3,000 RUR
- Complete repainting of the hood: 8,000β15,000 RUR
- Pasting with armored film: from 5,000 β½ per element
At dealerships, prices are 20-30% higher, but they guarantee a perfect color match.
How to choose paint for repairing a chip?
Look for the color code on your vehicle's plate. It may be located:
- In the doorway on the driver's side
- Under the hood on the stand
- In the trunk (on some models Volkswagen and Skoda)
The code looks like a combination of letters and numbers, for example, LA7W (silver) or B54 (blue). With this code, paint will be selected for you at a car store or mixed according to a catalog at a car service center.
How long after repair can I wash my car?
It depends on the materials used:
- Immediately after polishing.
- After applying the corrector - 12 hours later.
- After local painting - no earlier than 24 hours (preferably 48 hours).
- After pasting with armored film - after 72 hours (the glue must completely polymerize).
In the first 2 weeks after painting, avoid automatic car washes with brushes - they can damage the fresh paint.
Is it possible to paint over chips with regular spray enamel?
Technically yes, but the result will be noticeable. Cheap enamels (for example, Kudo or Abro) have three problems:
- Inaccurate color match (even if the code is correct).
- Lack of protection from UV rays - the paint will fade in a year.
- Poor adhesion - may peel off after several washes.
For high-quality results, use professional paints (Mobihel, Spies Hecker) followed by varnishing.
