After numerous light coats of shellac on walnut, I'm unable to remove
the light residue from the pores from either: dry sanding with 1000, wet
sanding 1000, gray or white pads. The shellac leaves residue in the
pores that I can't wipe out with a wet rag or by vacuuming. To remove
them I have to recoat. The problem is the sheen isn't PERFECT, so I
still need to buff the final coat. I tried wet pumice (dark gray) but
the sheen isn't what I want.

solution?
