After spraying, the surface of the car may appear coarse particles, sandpaper marks, flow marks, anti-white, orange peel and other small defects on the surface of the paint film. In order to compensate for these defects, grinding and polishing are usually carried out after spraying to improve the paint film. The mirror effect meets the requirements of brightness, smoothness and beauty.
Car polishing steps: 1. Clean the whole car. 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 coated surface, place a small rubber lining block with water sandpaper soaked in water before polishing, and lightly polish it until smooth.
3. Coarse and fine grinding. Use a machine grinder to add coarse abrasive paste to coarsely grind the traces of water sandpaper; then add abrasive paste to polish for fine polishing.
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 polishing. After the grinding and polishing, 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 beautiful.
