I picked up a 1977 Winchester 94 recently for fairly cheap. I want to refinish it for a winter project. The bluing on the barrel looks good but the reciever has/had some external rust that has taken off some bluing and left little freckles. Wondering what my best options are as far as removing them. I was thinking of removing the blueing on the reciever and trying to polish them out and then reblue. Mechanically the rifle looks like it was hardly fired. but the reciever needs some lovin. Thanks.
