I use a thin-tipped sharpie to sign the bottom of my work. Recently, I have been finishing and buffing the piece and then signing it over the wax. Will this quickly rub off? Should I put of coat of finish on the piece (I use antique oil), sign it, and then build the finish on top of the signiture? What do you guys do? My only fear is that if I sign the piece intially, it may smudge (even after the ink has dried?) when I go to put more finish over the signiture. What do you guys recommend?
