How to Repair Cracks in Car Body Shell?
1 Answers
If the crack is only in the clear coat layer, you can first use 1500-grit or finer water sandpaper to sand the crack, then polish it successively with coarse wax and mirror polish wax. Since the bumper is a plastic component, you can temporarily conceal it with decorations. When the insurance is about to expire, have it repainted along with other scratches.
