I let a buddy borrow my shotgun and I guess he didn't clean it after he was done and he just put it back in it's case and gave it back to me. Well I didn't check to see if he had cleaned it well tonight I pulled it out and the barrel looked like it had rust all over it. My question is how do you get rid of it and is it permanent? I cleaned it and oiled it up and put it back in the case but when I pulled it out a few days later it looked rusted again. Please help
Thanks
Eric
