Good point by Floyd. I have used Wurth HHS Plus fir years on door hinges & latches, it works and stays where it is shot. Another great product from Wurth is Rost Off Max Ice a freeze & penetrant spray. Rarely been able to coax old Ford brake line fittings out of wheel cylinders with out twisting the line in the process. Takes a few shots and alternating heat and they come out intact. Expensive, yes, works yes.
