Totally unscientific, but I have guns I haven't shot in a couple years that the last thing I did when I laid 'em up was to just run a patch with Ballistol through them. Checking them over, the barrels are still bright and shiny, so maybe it's better as an 'oil' than I thought.
It certainly ain't Cosmolene though. I wouldn't trust it beyond a couple years.
