Answer

For clear coat overspray, wet sand lightly with 1500 or 2000, refine with 3000, then polish.

Why it happens
Overspray sits on top of the finish and should be refined carefully to avoid cutting through the clear coat.
Recommended grit
Use 1500 or 2000 wet sanding for light overspray, then 3000 before polishing.
Wet or dry
Wet.
Success check
The rough overspray is gone and the surface has an even fine haze before polishing.

What to do

  1. Wash the surface first.
  2. Wet sand lightly with 1500 or 2000.
  3. Refine with 3000.
  4. Polish after sanding.
Avoid: Do not start with coarse grit on clear coat overspray.
