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.
