Here is my CZ-82 that I blued without a complete disassembly of the piece
. I DID strip it down as far as removing the trigger guard/slide lock. I disassembled the magazine release and remove the main spring and retainer. The entire peice was degreased and dried with compressed air. I glass beaded it after it was completely dry and blew out the loose bead with shop air. I cleaned all parts in Brownell's 909 cleaner and blued. I think it turned out pretty nice. <http://www.thehighroad.org/showthread.php?t=604882> You mileage may vary.
