I have a Marlin 30-30 that I let me uncle borrow a while back and I just got it back a few months ago. He had it over a year. Apparently my cousin got ahold of it and it was poorly taken care of. I spent an hour cleaning caked on Coke splatter and dust from it not being in the case. Please, no lectures on lending guns...I learned my lesson. Anyway, after getting the shit cleaned off I noticed there are some small "pin pricks" of rust on the left side of the reciever. How the hell can I repair this?? Guy at my local said i can "knock down" the pits with some #0000 steel wool and then just keep it oiled to prevent further damage. Any other ideas??
