I have two cans of this stuff that I use to spray the tracks on my garage door about every two years. It is a thick heavy yellowish grease that is carried out of the spray can with a volatile petroleum liquid which evaporates to leave the grease. The label on the can notes that it is "water resistant." This got me to thinking (no rude comments, please!)....would this stuff make a good rust proofing material? Has anybody ever tried using it for this purpose?
