I've been having a lot of fun lately cleaning up piles of parts with my media blaster. My focus has been on mostly doing cast aluminum parts and nuts & bolts, and experimenting with different media. Today I looked at my horns and they were horrible, so I took them off, gave them a cleaning, and reinstalled them. If anyone is interested, I've attached a few pictures of 'before' & 'after'. nasty, nasty.... but they cleaned up real well....
