I do rather like to use the products that where around at the time Black Powder was the main propellant. So for protecting gun barrels and other metal parts while in long time storage use a mixture of Goose Fat and Almond oil mixed to a fine soft paste. Though you must remove every trace from a shotgun bore before the gun is used other wise it may cause a ring bulge. Yes I know it does not sound correct for us modern types but it really works well.
As for wood polish a mixture of Bees Wax and Carnauba Wax to give some hardness to the finish dissolved in real turpentine with a small piece of Castile Soap added. This produces a soft sheen rather than a bright polish on an oiled gun stock and smells acceptable. Well in reality there are more formulas for wax polish than there are days in the year but this is the one I use.
