First, the paint surface oxidation conditions: the car under the sun's ultraviolet radiation, a long time will make the paint surface components have been dispersed, the brightness of the paint surface is greatly reduced, and because the car paint composition contains metal, etc., these substances determine the paint Easy to oxidize. As a result, the paint will slowly turn white, forming an oxide layer, shortening the life of the paint. The naked eye can be observed with the naked eye, whiteness, and dullness, giving the impression that the car is getting old.
Prevention: Waxing is the best way to prevent oxidation of paint. Because the wax acts as a seal, a protective film is formed on the surface of the vehicle paint, which inhibits the oxidation effect of harmful components on the exterior paint. Waxing must be divided into seasons. In the summer, UV-resistant waxes should be used.
Treatment: Oxidation of the paint can be treated by grinding and polishing. After grinding and polishing to remove the paint oxide layer, the vehicle can be rejuvenated and the color is restored to the state of the new car temporarily.
At the same time, it can also be sealed and coated. Sealing glaze can increase the sealing degree of car paint, and it is resistant to high temperature and ultraviolet radiation. The coating is applied to the vehicle body surface with a paint protection film, which plays a role in isolating and protecting the paint. This film itself is not subject to external oxidation, which is equivalent to "invisible car clothing."
Second, the traffic fouling illness: the car driving outside, it will inevitably stick insects, bird droppings, tar, etc. If they stay on the surface of the body for too long, it will produce a chemical reaction with paint, oxidation corrosion, plus The ubiquitous dust, your car will become unkempt and stained.
Prevention: Waxing must be kept in mind during daily care. It is best to make a wax once a month, but also before the rain, so as to play a sealing role. Do not look at a thin layer of wax film, which can be used to “cleanse” the dirt that you later clean up on the car, which has played a multiplier role.
Treatment: First, dilute the professional washing liquid in a certain proportion, directly apply it to the body with a sponge, rinse the foam with water, and wipe it with a special clean soft cloth. The washing powder, detergent, and towels that are used at will are not available. clean. Remember, the sediment must be removed and it must not be left behind.

Third, cracking illness: If you do not usually do some necessary care of the paint, metal paint may produce a very subtle cracks, it will continue to penetrate the car paint until the "break down" the entire paint layer, this phenomenon is called "Cracking". It usually happens on metallic paint. The early cracking of the cracks is difficult to detect, and it is already serious when the naked eye can detect it.
Prevention: Regular waxing can reduce cracking.
Treatment: Only paint thoroughly to the metal surface, then re-paint.
D. Fading Diseases: Contaminants are the main cause of paint fading and discoloration. Fading and oxidation are different. When oxidized, car paint becomes black and white, and when it fades, uneven paint color appears in the paint. The discoloration of metallic paint is caused by contaminated dust, acid and alkali corrosion in rainwater.
Prevention: To pay attention to daily care, car wash can reduce fading disease, mild fading can be treated by waxing.
Treatment: General use of colored wax, also known as color wax. The main effect of this type of wax is color enhancement, which makes the car paint more beautiful. The specific operation method is not much different from other common coating waxes, and it can generally maintain one month's time after nursing. Moderate discoloration can be treated with grinding and must be repainted when severe.
Five, shallow scratches Disease: due to friction and daily care in use, improper, over time, the car paint surface will appear a slight scratch, but did not expose the primer, this scratch is obvious in the sun.
Prevention: Wash the mud and sand as much as possible before washing, use a professional clean soft cloth to dry, or use a professional wiper, and do not use too much force.
Treatment: For shallow scratches, the owner can use polished wax. If it is serious, it must be handed over to a professional. After a series of meticulous treatments, such as grinding, polishing and painting, the paint will still be bright.
