Rennisance wax seems to be the preferred wax and is used by collectors. Yes it goes on just like waxing a car for the most part. Do not use a car wax with an abrasive added to it. I have used Johnson's paste wax for furniture, but read the directions. You do not let it dry to a haze and buff off. It's hard to get out of seams, screw heads, and lettering without some sort of brush. I find waxes hard to apply in areas that oil readily reaches. I have also used a Birchwood-Casey product called Barricade for years with good protection. But the guns look waxey/greasy, and aren't ready to show off with out a rub-down.
