The appearance of even microscopic damage to the paint coating (LAC) on the body is not just an aesthetic problem, but the first step to serious corrosion. Moisture and reagents, penetrating through the chip to the metal, trigger irreversible rusting processes that can spread under the paint in a matter of weeks. That is why the question of how to remove chips on the body of the car with your own hands is relevant for every owner who appreciates the durability of his car. ironhorse.
Self-repair of small defects allows you to save a significant amount compared to the services of specialized service stations, where an impressive check can be requested for repainting the element. The work does not require complex industrial equipment: a basic set of tools, selected in the tone of paint and patience, is enough. It is important to understand that the quality of the result directly depends on the thoroughness of surface preparation and compliance with the technology of applying materials.
In this article, we will discuss in detail the process of restoring the LCD, starting with assessing the scale of damage and ending with the final polishing. You will learn what materials are really needed and what you can save without losing quality. The main thing is not to delay with repair, since the removal of chips at an early stage is cheaper and easier.
Evaluation of damage and selection of repair strategy
The first step is always a detailed inspection of the damaged area. It is necessary to determine the depth of the chip: whether only the varnish is affected, whether the base paint is damaged or whether the corrosion has already reached the metal. Surface scratches are often managed to be masked with polishing, whereas deep chips require a more serious approach using restoration pencils or brushes.
If the metal has already begun to oxidize and red dots are visible, a simple paint won’t help – the rust must be completely removed mechanically. Ignoring this stage will cause corrosion to continue to develop under a new layer of paint, putting all efforts to naught. For diagnosis, you can use a magnifying glass or macro shooting on a smartphone to consider the structure of the damage.
- 🔍 Surface damage: only varnish is affected, metal is not visible.
- 🎨 Medium chips: the base paint layer is damaged, the soil or metal is visible, but there is no corrosion.
- ⚙️ Deep chips: metal visible, there are foci of corrosion, it is necessary to clean up to live metal.
⚠️ Warning: If the chip is on the edge of a door or hood where the metal is thin, the risk of through corrosion is maximum. Such areas require immediate treatment with anticores.
After the evaluation, a decision is made on the method of repair. For single points with a diameter of up to 2 mm, special restoration pencils or spot paint application with a brush are often used. If the damage occupies a large area or a lot of them (the so-called "pescoster" on the hood), local paint with detachment of the borders may be required.
Required tools and materials for recovery
The quality of repair depends on how well the materials are selected. The basis of success is the exact hit in the color of the body. To do this, the paint code is used, which is usually indicated on the factory plate (name plate) in the doorway or under the hood. According to this code, enamel is combed in specialized stores, creating a mixture that perfectly repeats the factory shade of yours. Ford Focus or Toyota Camry.
In addition to the paint itself, you will need a set of auxiliary tools. A degreasing agent is needed to remove silicones, oils and dirt that prevent adhesion. Soil enamel or acid soil are used to protect the metal and create a base for paint, especially if the chip is deep. Also, do not forget about polishing compositions for finishing.
The list of basic tools includes not only chemistry, but also mechanical devices. Fine grain sandpaper (P2000-P2500) will be needed for grinding irregularities, and a polishing machine or drill with a nozzle will help to achieve gloss. For applying paint, it is better to use a thin artistic brush or toothpick, since regular brushes in pencil bottles are often too rough.

Preparation of the working area and degreasing
Any instructions for repairing the body begins with a thorough washing and surface preparation. Dust, dirt and bitumen stains must be completely removed, otherwise they will remain under the paint layer, creating bumps and reducing the durability of the repair. Wash the car better with a special shampoo, avoiding aggressive household chemicals that can damage the integrity of the factory LCD around the chip.
After washing, the car should dry naturally or be squeezed with compressed air. The key is degreasing. For this purpose, a special antisilicone or isopropyl alcohol is used. The cloth should be clean, without pile, so as not to leave microfibers on the surface. Movements should be progressive, without strong pressure, so as not to smear the pollution.
| Materials | Appointment | Drying time |
|---|---|---|
| Antisilicone | Degreasing and removing silicones | 1-2 minutes |
| Rust converter | Neutralization of metal oxides | 15.30 minutes. |
| ground-enamel | Metal protection and adhesion | 20-40 minutes. |
| Basic paint. | Color restoration | 15-20 minutes (between layers) |
If metal and signs of rust are visible in the chip, it is recommended to treat the zone with a rust converter before degreasing. It turns iron oxides into a stable compound, stopping the corrosion process. After treatment with the converter, the surface is again thoroughly wiped with a degreasing agent.
⚠️ Warning: Do not use acetone or solvent 646 to degrease before painting - these may be too aggressive for factory varnish and leave matte spots around the chip.
Paint and lacquer technology
The most important step is to apply paint. If you use a restoration pencil, it needs to be shaken up. However, for the best result, paint is better applied with a brush. The technique is simple: type a minimum amount of enamel and carefully fill the chip, trying not to go beyond its boundaries. Excess paint will create a bump, which then have to be grinded for a long time.
The paint should be applied in several thin layers. The first layer serves as a soil for subsequent ones, so it can look semi-transparent. The interval between the layers should be 15-20 minutes for the solvent to evaporate. If you apply the second layer to wet paint, it can swell or go bubbles.
The secret of perfect hitting color
When coloring paint in the store, always ask to make a painting on a metal plate. Let it dry and compare with the body in different lighting - day and artificial. Metals and pearls can change hue depending on the angle of incidence of light, and on the plate it is easier to notice than in a small bottle.
After the restoration of color and complete drying of the base enamel (usually it takes several hours or a day), varnish is applied. Lacquer protects the paint from burnout and gives shine. It is also applied carefully, trying to form a small “lens” above the chip, which after polishing will merge with the general level of the body.
If the paint hit the undamaged area, do not try to erase it immediately with a cloth - smear it. Wait for complete drying and gently scrape off with a blade or remove with a solvent without touching the main layer.
Polishing and finishing of the surface
After the varnish is completely polymerized (it is better to wait 24 hours), the repair site will look like a bump. Abrasive polishing is used for alignment. First, a coarse paste is used to remove excess varnish and paint, then finely abrasive to remove the drawings. You need to polish carefully so as not to wipe the varnish to paint around the chip.
The ideal result is achieved by using a polishing machine with speed adjustment, but you can do it manually if the area of damage is minimal. The main thing is to control the surface temperature, since friction can heat the varnish and become viscous, which will make it difficult to polish.
- 🧽 Step 1: Wet the surface with water for the treatment.
- 🌀 Step 2: Apply an abrasive paste on the polisher.
- ✨ Step 3: Polish in circular movements until the tubercle disappears.
- 🛡️ Step 4Apply protective wax or ceramic composition.
The final touch is the application of a protective composition. It can be ordinary wax, synthetic sealant or liquid glass. The protection will create a hydrophobic layer that repels water and dirt, and prolong the life of the renovated site.
The quality of polishing determines the invisibility of repair. If the transition between the repaired area and the factory varnish is visible, the polishing procedure with a decrease in abrasive should be repeated.
Frequent Mistakes and How to Avoid Them
Beginners often make mistakes that reduce the result to zero. One of the most common is an attempt to paint a dirty or wet chip. The water remaining in the depression, under the action of the sun will heat up, turn into steam and swell paint from the inside. Always dry the chip with a hair dryer or compressed air before starting work.
Another mistake is to apply too thick a layer of paint. Instead of closing the defect once, enthusiasts pour a lot of enamel, getting a huge "snot". Remove it without damaging the surrounding area is extremely difficult. It is better to make five thin layers than one fat.
⚠️ Note: Do not perform repairs in the open sun or in temperatures below +15°C. Direct sunlight causes the solvent to evaporate too quickly, creating a shaverin ("orange peel"), and cold prevents the materials from being normally polymerized.
It is also worth mentioning the use of incorrect materials. Automotive paint is chemically different from household enamel or nitro. The use of inappropriate solvents can cause the factory LCP to dissolve around the chip, creating a crater. Use only specialized automotive materials.
Prevention of the appearance of new scalps
After a successful repair, you want the result to last as long as possible. However, it is impossible to completely insure against stones flying from under the wheels. However, there are ways to minimize the risks. Installation of anti-gravel film (armored film) on the most vulnerable places - the hood, bumper, mirrors - is the most effective method of protection.
Regular washing and application of wax compounds also play a role. A clean body with a smooth hydrophobic layer accumulates static electricity worse, attracting dust, and is also easier to clean from the aggressive chemistry of reagents. Distance on the track is another factor: following trucks without an increased distance is guaranteed to lead to sandy.
The myth of magnets on the hood
There is a myth that magnets on the hood collect metal shavings and protect against chipping. It's not. The shavings in the air fly at a great speed, and the magnetic field at such a distance will not have time to attract it, and the magnet itself can scratch the LCP when vibrating.
Compliance with these simple rules will allow your car to keep a tidy look longer. Remember that regular body inspection after the winter season helps to identify and eliminate minor defects before they turn into holes.
Can I paint a chip with a regular enamel from a can?
It is not recommended to use regular enamel, as it has a different structure, smell and resistance. Car paints are more elastic and resistant to temperature changes and ultraviolet light. Regular enamel can quickly crack or fade.
How much paint does it dry after repairing the chip?
The drying time depends on temperature and humidity. Usually the surface stops sticking after 1-2 hours, but the paint gains full strength and chemical resistance after 24-48 hours. During this period, it is not necessary to wash the car with aggressive chemicals.
Do I need to be covered if metal is visible?
Yes, I will. The soil provides adhesion (adhesion) of the paint with the metal and protects it from corrosion. Without soil, the paint can fall off a piece after a while, and the metal will rust under the coating.
What to do if the color of the paint does not match?
If the difference in color is noticeable, it is possible that the paint has burned out in the sun, and the new one is fresh. In this case, it may be necessary to switch (stuffing) or polish the entire element to align the tone. The code may also have been miscalculated when the scaling was done.
