I still have a can of the Johnsons wax from when I lived in AK and used it regularly on both my rifles and shotguns. The can must be 35 years old or more. I lived in western AK and unless it was winter, seemed to be always very wet and rainy. Oh yeah, I did use on my guns on a number of deer hunting trips to Kodiak, Afognak, in Cold Bay chasing waterfowl, Prince William Sound bear hunting and various other salt water environments and I never did get any rust, that I recall.
