Trying to go in order...
Hungarian - expect trouble

Hungarian's and Maadi's, while often ugly, have some BAD Ass paint on 'em. Aircraft Stripper or blast... they are THAT tough.
Bulgarian's - two differnt kinds of paint. "Old" Bulgy needs ZSTRIP, or other Hardware Store paint stripper. "New" Bulgy (like on an SLR106) will strip fast with simple Acetone.
krylon - or almost any other rattle can finish. Acetone generally eats this stuff faster than Paris Hilton can drop her drawers
