I bought a winchesr 1300 pump in 1980 brand new. Still have this shotgun and for the first 30 yrs I only wiped the outside down with WD40. Never used it on any of the internals but I hunted everything with that shotgun in all weather conditions. The blueing on that shotgun still looks as good as new. I would never use the stuff on any working parts but I have no issues using it on the exterior of any firearm in a pinch.
