Small defects on the paintwork are an inevitable reality for any owner who regularly operates his transport. Gravel on the track, flying stones from under the wheels in front of the trucks or careless parking - all this leaves characteristic marks on the body. Ignoring such damage can lead to serious consequences, including: metal-corrosion loss of the value of the machine in the sale.
Fortunately, not every chip requires an expensive visit to a specialized service and a complete repainting of the part. There is a proven algorithm of actions that allows you to restore the aesthetics and protective properties of the coating at home. Well-chosen enamel And the accuracy of the execution works wonders, making the damage almost invisible to the prying eye.
In this article, we will discuss all the stages of work: from the initial assessment of the scale of the disaster to the final polishing. You will learn what tools are really needed and what you can save on, and how to avoid the typical mistakes that turn a small cosmetic defect into a huge โpumpledโ problem.
Evaluation of damage and selection of restoration method
Before grasping the tools, it is necessary to soberly assess the depth of damage. The paint coating of the car is multilayered: on top there is a varnish, under it there is a base paint (color), then the soil and, finally, the metal of the body. If the chip touched only the varnish, it will be enough to hold a quality polishing Abrasive pastes.
The situation is complicated if the paint layer is damaged or, worse, the metal is exposed. In the latter case, you can not delay: moisture and reagents from the road will immediately start oxidative processes. For such cases, there is a method of local paint, often called โpoint repairโ. It requires precision, but it gives a great result.
โ ๏ธ Note: If the chip has torn edges or paint has swollen around it, this is a sign of corrosion that has begun. A simple paint here will not help - you will need a strip to the metal and processing with a rust converter.
It is also important to consider the type of paint on your car. Metals and pearls require more sophisticated application technology, as metal particles must be properly orientated in the layer to match the color with the main tone. Regular acrylic enamel (solid) forgives more mistakes and is easier to polish.
Required materials and tools for the work
The quality of the result depends on what you do. Using a stationery proofreader or inappropriate paint is the way to create an indiscriminate defect, which will then have to be drilled. You will need a specialized set of materials that can be purchased in auto shops.
The basis of success is the accurate selection of color. The paint code is usually on a plate in the doorway or under the hood. Even knowing the code, it is better to make a painting on the test surface, as the factory paint burns out over time and changes shade. The work will also require a degreasing agent, microfiber and applicators.
- ๐จ Retouching enamel (in the form of a pencil, a bottle with a brush or aerosol) selected by color code.
- ๐งช Degreasing (antisilicone) for surface preparation.
- ๐ Abrasive polished paste (preferably fine-grained).
- ๐งฝ Applicators, toothpicks or thin brushes for spot application.
- ๐ก๏ธ Lacquer (2K) for finishing if deep chipping is reconstituted.
Do not forget about personal protection. Pairs of solvents and paints are toxic, so work should be in a well-ventilated room, preferably using a respirator. Gloves are also required to avoid leaving fat marks on the prepared surface.
Buy the remake from official brand dealers or in specialized color studios. Cheap universal sets often give a strong variety and fade quickly.
Preparation of the surface for the restoration of LCP
The most important stage at which many beginners make fatal mistakes is preparation. Applying paint to a dirty, greasy or wet surface will cause the material to simply not lie down or peel off after a week. The body should be perfectly clean and dry.
First, the car is washed with shampoo, paying special attention to the repair area. After drying, the chipping place is carefully cleaned. If there is oxidized metal, it is removed with a thin blade or needle. The edges of the chip can be slightly passed with a small abrasive (for example, P2000) to remove sharp transitions, but do not overdo it.
The final touch of preparation is degreasing. Use a special car degreaser, wiping the repair area and the area around it. Do not use gasoline or aggressive solvents, they can damage the entire lacquer coating. After that, touching the treated area with your hands is strictly prohibited.
| Phase | Tool. | Purpose |
|---|---|---|
| Washing | Shampoo, sponge | Removal of dirt and bitumen |
| Cleanup. | Needle, blade. | Rust removal |
| Degreasing | Antisilicone, napkin. | Fat film removal |
| Suit | Compressed air | Removal of moisture from the chip |
Paint and lacquer technology
The application process depends on the depth of the chip. If only the color is damaged, use a thin brush or needle. We collect the minimum amount of enamel and carefully fill the recess. The paint should be level with the main coating, but not higher. The surplus is removed immediately.
When deep chips to metal, we act in layers. First, the soil is applied (if the area is large), then the base (color), and only after the base is completely dryed - varnish. Lacquer creates a protective film and glossy shine. It is important not to transfuse the material, otherwise leaks are formed that are difficult to remove.
โ ๏ธ Note: Do not try to paint a large chip at once. Multilayer application with intermediate drying (10-15 minutes) will provide better adhesion and no bubbles.
There is a technique of โmicro-dropsโ, when the paint is applied point-by-point, allowing each layer to dry. This allows you to control the volume of the aggregate. For metallic, it is important to apply the base with light movements, without rubbing aluminum particles chaotically, otherwise a stain will appear.
โ๏ธ Paint control
After all the layers have been applied, the car takes time to polymerize. Even if the surface is dry to the touch, the chemical processes inside the material continue. On the first day it is better not to wet the car and not to expose it to chemistry.
Finishing and polishing of the transition
After the paint and varnish are completely dried (ideally wait 24 hours), you can start finishing. Often the repair site looks a little bulging or matte. The task of this stage is to level the repair area with the main coating and return the shine.
We use abrasive polishing paste. We apply it to the polishing circle or manually (if the area is small) and treat the chipping place with circular movements. You need to act carefully so as not to wipe the varnish to paint on the surrounding body.
- ๐ A large abrasive removes irregularities and a โstepโ between new and old paint.
- โจ Fine abrasive paste returns transparency and deep gloss.
- ๐งผ Protective wax or ceramic coating fixes the result.
The result of correct polishing is a homogeneous surface on which the repair site can only be found on very close examination. If the transition is still noticeable, the polishing procedure can be repeated, but with less intensity.
The Secret to Perfect Polishing
Use a magnifying glass or bright light at a sharp angle to see micron irregularities. Polish until the glare of light is uniform across the surface, without refractions at the chipping boundary.
Common Mistakes and How to Avoid Them
Even following the instructions, it is easy to make mistakes due to lack of experience. One of the most common problems is the โorange peelโ or shaking at the repair site. This happens if the varnish or paint is applied too thick or at high ambient temperatures.
The other extreme is insufficient adhesion, when the paint falls off in pieces after a month. The reason lies in poor degreasing or getting moisture into the chip before painting. Also a common mistake is to ignore the temperature regime: you can not paint in the cold or under the scorching sun.
Do not try to disguise the chip with a wax pencil if you plan to do a full repair later. Wax compositions clog the pores of the metal and interfere with the normal adhesion of the paint. They can only be used as temporary protection against rust before sale or seasonal storage.
โ ๏ธ Never use household solvents (acetone, 646) to dilute car enamels unless you are sure they are compatible. This can lead to the collapse of the paint and a chemical reaction.
Remember that not everyone gets the perfect result the first time. If the chip is in a prominent place (hood, trunk lid), it is better to practice on an inconspicuous detail or the inside of the door. This will give you an understanding of the behavior of the materials.
The main rule of restoration is to make five thin layers with intermediate drying, rather than one thick layer that will float or wrinkle. Patience is the masterโs main tool.
Frequently Asked Questions (FAQ)
Can I paint a chip with a regular enamel from a can?
Using an aerosol can for spot repair is extremely difficult due to the wide spray torch. You risk dusting half the car. For small chips, use vials with a brush or a syringe dispenser.
How much paint does the car dry?
The drying time depends on the type of enamel and temperature. The base paint dries "on a stick" for 15-20 minutes, but the full strength gains several days. The lacquer is polymerized for about 24 hours at a temperature of +20 ยฐ C.
Do I need to lay a small chip?
If the chip to the metal and its diameter is less than 1-2 mm, modern soil enamel or epoxy bases allow you to do without separate priming. For large areas, the soil is mandatory for protection from corrosion.
What to do if the color does not match?
Factory paint burns out over time. If the new material looks brighter, you can try to slightly polish the transition to level the visual perception, or use color additives to age the tone (requires skills).
