I use the same wax on all my guns. beats the oil feel and protects better!Wax will protect the steel and wood from moisture and fingerprints. I used Johnson's Paste Wax on my shotguns when duck hunting, and never had a problem, even when my wet Lab stomped all over the guns!
I freely admit that I do not know everything.Strange, but this is the first I have heard of waxing guns. Sounds like a good idea.
