What's the best stuff for breaking loose old rusty nuts and bolts? So far all I've got is trusty old WD-40, but I wonder if I should step up to something better when I start redoing my suspension. What works the best?
We used to get some stuff from the Chrysler dealer that was made to break free rusted exhaust bolts. It was in a spray can and cme out like a foam. It was the baddest I have ever seen. Lately we use either PB Blaster or JB80 from Justice Brothers. Both of them seem to work well.

I have a can of some of that foaming stuff as said above. ALthough the can is black silver with no label on it, I know it is a Power Up penetrating lube. Rather expensive, but it works really well... and the smell is sweet, no headaches.
WD-40 was apparently initially designed for use by the military to keep condensation off of missile warheads. WD -> Water Displacement. WD-40 is good when used to keep water off of things. I like to spray it in between the car body and the mudflaps, as a lot of water tends to get caught in there after a wash and might cause rust. It also cleans your hands well!
