Automobile paint occupies an absolute dominant position in automobile aesthetics. Car owners should miss the days when they first got their new cars. Even if it is not a luxury car, the beautiful new car shines on the street, winning passers-by to turn back frequently. Good times are always short. Paint killers are everywhere. After a period of use, the wind blows around, and natural factors such as flying sand, moisture, acid rain, bird droppings, industry, dust, ultraviolet rays and so on will invade. Coupled with human factors such as poor car washing (alkaline car washing liquid, scratches on car washing) and lack of maintenance, car paint will lose its luster, fade and crack due to aging. ? Car paint is the most fragile part of the car body, and car paint itself is also a kind of chemical, which is fragile. Car paint needs cleaning and maintenance just like human skin, but car paint maintenance should not be sloppy. ? What if there are yellow spots on the paint? ① The source of yellow rust spots is mainly the yellow rust spots formed on the paint surface after iron powder floats on the paint surface and rusts in the rain or fog, and another is the yellow rust spots formed by rust powder floating on the paint surface. Yellow rust spots on light-colored paint are easy to find, such as white cars and silver cars, and dark cars are not obvious visually. Generally, car washing is difficult to clean, and it will penetrate into the paint surface for a long time, making it more difficult to clean. There are one or two yellow spots in the local position, so it is necessary to check whether the paint film is damaged, scratched by sharp objects or hit by high-speed stones. If the paint film is damaged to the iron sheet, and yellow rust spots are formed on the paint surface after being corroded by rain or fog, then you should go to the 4s shop in time to ask professionals to derust and repair the spots on the surface, and then repaint it to avoid large-scale rust and rust wear. ? (2) Whether the whole vehicle has yellow rust spots, including front and rear bumpers, door handles, rearview mirrors, etc. Such problems are mainly related to our parking environment (construction site, rusty parking shed, etc. ), and the paint has not been cleaned for a long time. Therefore, we need to clean and maintain the paint surface regularly according to the usage of the vehicle. ? What if the car paint is scratched? 1 hair cut? Definition: Facing the light, you can observe the thin lines on the car paint, but generally you can't touch them with your hands. ? Countermeasures: Wax with fine-cut abrasive can be used for polishing. ? ② Slight abrasion? Definition: Sometimes when naughty children pass by, they will gently cross the car body with their keys, leaving obvious scars on the car paint. In fact, this only hurts the transparent layer on the surface of the car paint. ? Countermeasures: Use fine cutting or medium cutting wax to polish. ? ③ Moderate scratch? Definition: Heavy scratches directly hurt the paint layer, and the paint layer can be clearly observed and touched. ? Countermeasures: Thoroughly clean the damaged parts, choose the touch-up pen closest to the car color for repair or go to the 4S shop for repair, and do not wash the car within three days after the touch-up is completed. ? 4 deep scratches? Definition: scratches on the car body directly expose the car body metal plate. ? Countermeasures: drive the car to the 4S shop immediately, and ask the professional master to redo the antirust primer treatment for you and spray paint the surface for repair. If the injured car paint is not repaired in time, corrosive substances will slowly oxidize, leading to rust and deterioration of the wound surface, resulting in greater losses. ? Warm reminder? (1) when driving on the road with poor road conditions, slow down to reduce the damage of stone impact on the paint surface of the car body; ? (2) According to the usage of the vehicle, it can prolong the service life of the vehicle by regularly checking the damage of the paint surface of the vehicle body, finding the problems in time and handling them in time; ? (3) Try to avoid parking in places with poor environment such as construction sites and seriously corroded parking sheds; ? ④ Regularly clean and maintain the car body.
