I was going to go there, you beat me to it. WD-40 does a decent job as a penetrant, and is okay - not great - as a water displacer. It's my first choice for shooting into cracks and stuff, but that's only until I can get parts loose. Then I reach for grease or something else that'll actually stay around for a while.

As to shooting it onto brake discs, I wouldn't be too concerned if it was done, but I'm not about to go doing it on purpose, either.
