RC, I have a buddy that does the same thing, rusts everything he touches... Go to hand him a pistol or a rifle and he will throw his hands up and say "No I'm a Ruster!" sad thing is, he is one of the most skilled machinist and motorcycle mechanics I have ever known... But he is right. where he touches, wipe it,oil it or it will rust!!.
As far as Waxing, I know several that do wax their guns, some duck hunters that are always exposing to rain, wet and mud, Motorcycle Officers, a couple that do, because their pistols get the worst of treatment, and a few revolver match shooters, claim that it cuts down on the powder buildup.. makes sense, I've just personally never done it..
