Re: SUGGESTIONS FOR FINISH PROTECTION AND STORAGE.
Renaissance wax is OK for guns that will not be used at all. It is a favorite for museums where guns (or other metal objects) will be displayed in cases and never touched or handled, let alone fired. The same is true of elaborate air removal or inert gas systems.
VPI paper is also good, but has a limited life span.
But most gun owners don't want to put their guns out of touch for years or decades, they only want to prevent rust and corrosion in a gun safe or a cabinet. For that purpose, I have used several types of preservative, including G96 Gun Treatment, which sprays on easily and doesn't build up like some. I don't use WD-40 because I have found that under adverse conditions, it can itself mildew and harm wood or metal finish.
I generally clean a gun reasonably well, spray on the G96 and (if a handgun) put in in a plastic "baggie"; sealing is not necessary, but is OK. Then in a box and into the safe. The baggie is inert, blocks moisture and keeps in the penetrant fumes. The safe is protected with a "Golden Rod", but a simple low wattage light bulb will work about as well.
