My buddy has an old pre saftey model 94 with about 50% of the finish remaining. His grandfather found it in his garage and gave it to him for a deer gun. The other day he asked me if I knew how to clean this thing up and I told him I did not know where to start but I would be glad to help. So how do I get the rust off this thing and save the blueing? Also feel free to share experiences you have had with saving a finish. Thanks.
