Being that I have half of the enemies to a gun.
My Para 1911 has rust on it. Mostly inside the magwell where the paint has worn off. The finish on the rest of the pistol is starting to wear in places, and the thing on the back that is designed to rip off large chunks of your palm while racking the slide (and can ostensibly serve as the 'rear sight' from time to time) has also gotten a little rust on it as well.
Dangit.
I gotta burn through 150 rounds or so of .45 ACP since it's a bit on the hot side for competition. Don't know when I'm going to be able to do that though since the Mrs. managed to catch my cold so I'll be doubly busy this week and then will be pretty much swamped with soccer and plays over the weekend. So it's not like I'd be able to make this months shoot as it is.
So, what's your favorite rust removal technique? I have a sharp stick to poke the 'steel wool' commenters, so be wary.
