I have a plastic model with Tamiya white primer, then a coat of Tamiya matte white, and finally a topcoat of Tamiya Peral White. Then I painted part of an area flat black, but missed a part of the masking, and some black overspray got on the white.
I sanded it with 1000 grit dry, and re-painted. But I can still see sort of a "shadow" where the black paint was.
How can I re-do it, and eliminate the "shadowing"? My guess is that I might have sanded too hard?
