Old Colonel - I use Renaissance Wax on the wood and EEZOX IN the barrels and ON the barrels.

I do this to protect ALL my firearms, including my vintage percussion shotguns and rifles that use blackpowder.

Now, you know BP and petroleum products don't go well together, so before I use these muzzleloading shotguns and rifles I get rid of the EEZOX oil with denatured alcohol.

Works like a charm.
