How to repair the car paint off? How to repair the car paint if it is serious

The solution to the car paint is to use a paint repair pen for coloring, which can prevent the embroidery from expanding and aggravating. There are generally four basic components of automotive paints: film-forming substances (resins), pigments (including physique pigments), solvents and additives.

The film-forming substance is the main component of the paint, and its function is to keep the pigment in a bright state, make it strong and durable, and can adhere to the surface of the object, and is the substance that determines the type of paint. Pigments are one of the two non-volatile substances in paints that give topcoat color and durability while giving paint hiding power, as well as improving strength and adhesion, changing gloss, and improving flowability and coating properties. The solvent is the volatile minus component in the paint, and its main role is to fully dissolve the resin in the paint film, so that the paint can be applied normally.

Additives include curing agents that speed up drying and enhance gloss, and retarders that slow down the rate of non-drying.

If the car paint is dropped, go to the car beauty shop or 4S shop to do partial touch-up paint or repaint. If it is a slight scratch that needs to be seen carefully, it can be wiped off by wiping it twice with a wet towel, and it can be waxed directly, even if the mercerized wax effect without abrasives is good. If it is deeper but has not yet lost the primer, you can use a touch-up paint pen, shake it before use, so that the paint inside is evenly blended, and after the touch-up paint pen is dry, then use fine wax to hit it, and it will be as bright as the original paint.

Before, during and after the use of the vehicle, the dust on the vehicle body should be removed in time to minimize the adsorption of dust by static electricity on the body. Rinse promptly after rain. After the rain, the rain stains on the car will gradually shrink, so that the concentration of rainwater acidic substances will gradually increase, and if the rain stains are not rinsed with clean water as soon as possible, the topcoat will be damaged over time.

1.Wash the part to be repaired before touching up the paint, and the scratch marks that are not too damaging to the car paint can be directly wiped with a scratch repair agent.

2.Deeper scratches can still be smoothed out with a repair agent, and the remaining scratches that are not easy to deal with can be repaired by spraying the paint layer on the brush.

3.For more serious scratches, fill the pit with soil first, smooth it with coarse sandpaper and fine sandpaper after drying, and then paste the places that do not need to be painted with stickers, and then spray anti-rust primer, color paint layer and varnish layer in turn, and finally remove the stickers and smooth the surroundings with scratch wax.

If the paint is small, you can touch up the paint locally. If it is large, it will need to paint the entire part.

If the car paint is off, it is best to find a professional to repair it.

If you hurt the body primer or even sheet metal deformation, this situation is already very serious, and if it is not treated in time, it will develop into rust later. To repair the undercoat and deformation, the paint is sanded off, the sheet metal is repaired, and the coats of paint are reapplied. This condition is relatively expensive to repair and is best repaired by an experienced master.

Slightly scratched paint damage is mostly on the surface of the topcoat, not very deep, this can be completely repaired by waxing, and will not leave a bad paint surface. The cost of waxing is not very expensive, and if you have a good relationship with the master of the repair shop and it is not a serious injury, he may also treat you for free.

3. Damage to the body topcoat.

If the scratches are deep, or even part of the topcoat is scraped off, but the primer is not damaged and there is no serious deformation, the paint can also be restored better by waxing.

How can I tell if the primer has been damaged? If the body is not white, observe the color of the scratches on the body, if the color of the scratches is the same as the color of the paint on the body, it means that the primer is not damaged; If the body is white, since the primer is generally white, it is necessary to judge whether the primer is scratched and checked by a professional painter.
