Turning to the putty painting process, vehicles with good appearance will drive to the putty scraping place, and the putty will be polished and leveled by a professional putty scraping master, and then the putty will be dried and leveled with sandpaper. In the process of primer spraying, after the putty is scraped clean, it should be very flat and smooth to touch by hand, and then the primer needs to be sprayed. After the primer is sprayed, you need to wait for a period of time, and then use fine sandpaper to grind off the points on the primer with water to make the paint surface smooth and flat without holes.
