Nice to read about someone who really gets the value and magic of WD-40. Don't leave home without it ! If I had to choose only TWO products to use for working on and treating things on cars, WD-40 would be one of them. heck..for really severe cases perhaps a cockpit actuated system that mists down the entire engine compartment ! just joking . But the stuff is magic.
