1. Clean the whole vehicle. Use a paint cleaner with strong detergency to clean the entire vehicle. When using the cleaner, avoid particle dust from causing new scratches during grinding.
2. Polished with water sandpaper. For defects such as coarse grains, fine sandpaper marks, flow marks, etc. on the coating surface, before polishing, use 600#~1000# water sandpaper soaked in water to wrap in a small rubber liner, and lightly polish it until it is smooth (be careful not to wear through Paint layer).
3. Coarse and fine grinding. Use a machine grinder (electric or pneumatic) to add rough grinding paste to rough grinding the traces of water sandpaper; then add grinding paste to polish for fine grinding.
4. Polishing. Using a mechanical polishing machine, plus mirror surface treatment agent to throw away the spin print left by the rough grinding paste, to achieve the effect of mirror polishing of the paint film.
5. Manual glazing. After the polishing is finished, wipe off the polishing paste, and immediately wipe all the polished parts with cotton yarn dipped in varnish wax, and then use dry cotton yarn to wipe off the excess glazing wax to make the paint surface bright and dazzling.
After the surface of the car is sprayed, there may be small defects on the surface of the paint film such as coarse particles, sandpaper marks, flow marks, reverse white, orange peel, etc. In order to compensate for these defects, the car polishing process is usually carried out after spraying to improve the paint film. The mirror effect meets the requirements of brightness, smoothness and beauty.
