I have this littel piece of crap Kel-Tec p11 that is exactly one month old and is already showing RUST! I am so mad. I keep it clean and lubed, but after 4 weeks of carrying it, the thing is already showing rust. Anyway, I'm curioius what the best chemical is to get that rust of of there. I'm thinking about duracoating it to prevent this from hapenning again, but I need to ge the rust off first. any ideas?
