Remove small cavities and paint grains with a honing stone or wet-or-dry sandpaper.
Start with a rough wet-or-dry sandpaper and finish up with a fine P2000 to P3000 paper.
2.
Finishing of Painted Surface: Sand the painted surface in one direction with water or soapy water using P1200 to P3000 wet-or-dry sandpaper to flatten the surface. Wipe off any remaining sanding particles using a cloth.

Matching Surface Quality and Polishing:
With fine compound, polish the surface with a polisher set with a towel buff or intermediate sponge buff to remove hairline sanding scratches. Finally, polish it out with finer compound.
Remove compound residue frequently to avoid damaging the paint surface.
NOTE: Turn on the polisher power switch after it is touching the painted surface.
4.
Move the polisher along the panel surface parallel to the ground (horizontal direction).
5.
Where the paint is repaired in gradation, move the polisher from the newly painted area to the old painted area.
NOTE: Moving the polisher in a wrong direction may expose the paint border.
6.
Hand-polish the stamping lines or near weatherstrips.
NOTE: Machine polishing may remove too much paint from stamping lines, so hand polish these areas.
7.
Apply more compound for finessing. Move it in a horizontal direction for the final polishing.
