Answer

For clear coat dust nibs, wet sand lightly with 1500 or 2000, then 3000 before polishing.

Why it happens
Dust nibs need very fine leveling so the surrounding clear coat is not cut too aggressively.
Recommended grit
Use 1500 or 2000 for nib leveling, then 3000 before polishing.
Wet or dry
Wet.
Success check
The nib is level and the area has a small even haze before polishing.

What to do

  1. Let the clear coat cure as directed.
  2. Wet sand the nib lightly with 1500 or 2000.
  3. Blend the small area with 3000.
  4. Polish after the haze is even.
Avoid: Do not use coarse grit on small clear coat dust nibs.
