I posted this in the gunsmithing but thought it might be better in here. The previous owner of my kimber royal II didnt not keep it oiled like he should have. I have tried a few different polishing things I have read about but cant get all the discoloration off. I was thinking of getting some of the birchwood casey perma blue to cover up the discoloring. Is there any reason I should not do this? If not does anyone have any tips for applying it? Thanks Wanna kill these ads? We can help!
