We would be surprised how durable a wax finish is on metal. In 1987, I bought a 682 Beretta that had the standard Beretta, almost parkerized, finish on the barrels. I didn't like it, so applied a coat of my Mom's Johnsons Paste Wax and buffed it well. Today, it is still shiny and shows no sign of returning to the factory matte finish. I don't remember ever redoing it, although I may have once.

Butchers Bowling Alley Wax.

Allen got us onto wax on the wood but am I understanding that everyone else is referring to using the various types of wax mentioned on color case hardening? I understand the wax is ok for the barrels but is it ok for the case hardened areas?

Bill are saying the Dr. used Bhelins wood finish on Damascus barrels? Really?? Right from the horses mouth.
