Has anyone used this for guns that are mostly kept in storage? How often does it have to be re-applied to keep rust at bay?
An uncle is in his mid-80s but still keeps a shotgun at home. He used to rely on his favorite combo of Hoppe's 9 and Break Free for cleaning stuff but is now more sensitive to chemicals and strong odors. I bought a can of Ballistol for him to try but I have no experience with the product so I'm not sure how well it works for rust protection. The only other stuff I have on hand that I can give him is Lucas CLP but am not sure if Lucas is as mild/non-toxic as Ballistol.
