O.k. Here it goes. I has pf9 blued that has not been shot due to a surgery I have had but I have snap caped the crap out of it. Back when the post 9days and rust started i looked over my PF and behold I have rust on the barrel. Crap, so I have polished other barrels and had 300,600 and 1000 grit wet/dry sand paper. I use a little gun oil on the paper and sand down the barrel, it cleans off nice not a mirror image but enough to clean off rust. About 2 weeks later I check again and now the rust is returning. Sooooo this time I polish with sand paper to a mirror image and Finnish off with mothers car wax, wipe down and added a thin layer of car axel grease. Now about 2weeks later I have a look and I can see little specks forming on my mirrored barrel. These specks were not there before. I can not find a speck of rust on the rest of the pistol any where. They are kept in a small safe that holds a couple other pistols with loose mags. I have a bunch of the silicone packets and containers you get in pill/vitamin bottles all over the place including my ammo cans. What else can I do? how can I stop this from continuing? How come my other pistols with polished barrels don't have this problem? Thank's for any help y'all can provide.
