I picked up a S&W 22-A from a local pawnshop for a song yesterday. I wasn’t looking for one, but it was too good to pass up. Anyway, previous owner attempted to pain front sight white (and made a real mess of it). Appears to have a painted on type of finish which is why I’m asking… If I use acetone or something like that, will it take off all of the finish, or just the white? Ideas. Thanks!
