How to repair deep scratches on car paint
If the paint surface encounters deep scratches, without damaging the primer, you can repair them by following these steps:
First, use #1500-2500 grit sandpaper to sand until the surface is matte and smooth.
Next, use a DA polisher with a long wool pad and medium-fine abrasives to polish.
After polishing to a glossy finish, use a mirror polish pad and fine abrasives to restore the mirror finish.
