After the electric vehicle is damaged due to deformation and other reasons, there will be some defects that cannot be remedied after the correction of the body metal of the electric vehicle. In order to make it more perfect and exquisite, we must use sculpture technology to make up for the defects. These works must involve the body and paint of the vehicle. The following is a brief introduction by the auto parts manufacturers:

I. body and paint type:

1. Common paint is a simple common automotive paint. It is characterized by low cost and simple process, but its glossiness is not good, and its surface hardness is not high, especially easy to scratch. So although this kind of paint has advantages in price, it is rarely used in cars, mostly in trucks and buses.

2. Metallic paint, also known as metallic flash paint, is a popular automotive finish. The metallic paint is based on the common paint plus aluminum powder, which is also protected by a layer of varnish, so it looks very bright after completion. The main feature of metallic paint is not only its high brightness, but also its hardness is much higher than that of ordinary paint. It is not easy for ordinary objects to scrape it off. Therefore, metallic paint is basically used in cars, especially in high-end cars.

3. Pearlescent paint, also known as mica paint, is also a popular automobile finish. Its principle is basically the same as that of metallic paint. Pearlescent paint gives people a new, colorful and dazzling feeling.

II. Paint treatment

Paint surface treatment is the next process after finishing paint. For some electric vehicle loading paint, there will be slight fine fish scale, which is a natural phenomenon caused by the dry time difference of paint film in the leveling process. We usually can't detect it. If we want to cheat the eyes of experts, we have to do paint surface treatment, which we usually call Is specular. Use the beauty sandpaper for leveling and grinding, and then use the coarse wax composed of pumice or clay to grind and cut to remove the traces of sandpaper. Next, use the fine cutting wax to grind to remove the traces of coarse wax, and then use the reducing agent to achieve the perfect luster, and then use the mirror surface treatment agent to completely remove the halo and scratches. At this time, the paint to achieve the deep luster, and the next process is glaze sealing. In this way, the perfect paint effect can be achieved.
