What is it with WD-40?

Furniture wax works best to protect the finish on both blueing and wood stocks. You don't oil the surface of your car to protect the paint.. why would you put oil on the outside of your gun. Like said, oil is a lubricant not a preservative. Seal the surface wax or grease for long term metal storage. Oil plus water = oil on surface, water on the bottom , on top of the metal surface. Grease plus water= water on top, grease on the bottom sealing surface. Just FYI. Nothing to do with the topic. I used and still use Pledge furniture wax on all firearms. Just wipe with soft cloth after handling. No prints or rust after 40 plus years at home and 20 plus years in my old gun shop.
