I am only recently learning how to properly care for a gun, my poor shotguns lived sealed up in old cases and now need some help, I'm going to have to recoat my old Mossberg 500.

I am woodworker and we've always used various types of wax to prevent corrosion on all our steel and cast iron machines

Does this have any use for the exterior of our firearms?

In particular I am thinking of the microcrystalline waxes like EJ-Wheaton or Renaissance Wax. Both of them are excellent on wood stocks, and are very often used on metal, leather, and stone objects in museums.

In the cabinet shop we also use Johnson's and Minwax basic paste wax on the machinery.

I know there's a lot of oils made just for this and I'm open to suggestions here, I was just curious if anyone used wax on their firearms.
