As I don't have any more Cosmolene any more, would liquid Alox or something thinner like BLL be a good rust preventer in bores that might not be shot for a few years? I live in a relatively dry climate so rust isn't a real big concern, but I would like something a bit more longer lasting than an oil type product. I think I heard that it was originally developed as an undercoating for rustproofing cars, so it should work on the outside of a gun also.
Any comments?
