Due to my idiocy I left my black supernova in my paded case over night after a salt water hunt and the rust has gone through in some places to the metal. Can redo the barrel myself? It is a polymer coat so blueing won't work correct? Any advice on how to redo it (how to + materials required etc) or were in the lower mainland of British Columbia I can take it that would be helpful. It's only 2 years old and I don't want a spotted finish on my baby.
