RE: Surface rust on gun
My mother recently gave me my father's old 12 gauge shotgun. It was a single shot made by Cresent Arms and the last one that they made was in 1930, so it is at least 74 years old. My father had passed away in 1991 and I had lived out west until just recently. The gun had sit in the closet since Dad passed away and was literally covered in rust. The WD-40, gun oil, and along with some very fine steel wool done an excellent job on this gun, the barrel amost looks new. I have had several people comment on how nice this gun looks and it certainly has great sentimental value for me.
