I'm curious, maybe one of the chemist-types can answer this?

I was under the assumption that a blued finish, at least as pertains to firearms, requires a continual application of oil to prevent red oxide aka rust from forming on the surface. Obviously based upon some of these posts this is not the case.

So what's up re. the wax? Does it supplant the need for oiling, or is that also still required as well?

thanks,
Dave
