Just a little precaution on using WD-40, being in the gun business I have seen and used many types of metal protection and know that WD-40 displaces moister by absorbing it. While it works fine (and smells good too
) if you wipe down the item frequently. If using it alone it will after time absorb atmospheric moisture and cause rust. Browning even warns not to use it or Rem oil. To use it is fine but use it often especially in an often damp environment such as a basement. Now I know may have used it for years with great results but just keep the above in mind.
