The clear Carnuba would be okay, but just save a lot of money and go to any hardware, most Walmart's and some grocery stores and buy a big yellow can of Johnson's Paste Wax.
This works just great and a can lasts forever.
I use it as a release agent when using epoxy.
Wax is the only thing you should use on holsters.
You can apply a coat to guns instead of oil or grease to prevent rust while storing.
If you apply a medium-heavy coat to a pistol frame area that's covered by the grips and don't wipe it off, just let it dry 20 minutes and put the grips back on, the frame won't rust from sweat and moisture that leaks under.
It works great on all wood, including rifle stocks.
If you apply a coat under the wood of a hunting rifle just like pistols, it won't rust in damp woods.
Salt water duck hunters often apply a heavy coat to their shotguns, warm it up with a hair dryer until it melts, then let dry and lightly wipe off the excess, their guns don't rust.
Did I say it's cheap and easy to find?
