If any section of the clear coat is removed, the whole body panel must be repainted with clear coat. Secondly, always use the right tools. For example, using a high speed buffer will burn paint, leave wheel marks and remove too much clear coat. Be especially careful when using these tools and only use them if necessary. Do not use a cross-hatch motion.
Checkerboard patterns are very difficult to remove and smooth out.
Mild Paint Contamination Repair procedures vary from vehicle to vehicle and depend on the severity of the damage. Mild spotting conditions can usually be fixed with hand polishing. Minor etching, orange peel or smudging of the clear coat layer can be reduced with light wet sanding, followed by hand buffing and polishing. If the spotting and etching damage is still present, a more aggressive cutting-type repair will be required. When a painted metal surface has been scratched or chipped, it should be touched up as soon as possible to prevent corrosion damage.
