it wasn't him. He doesn't have a parts car. :)
ol' 81Black still lives over 2 hours away from me.

I just want to point out that melting a styrofoam cup has NOTHING to do with busting a rusted bolt. Gasoline melts styrofoam really well, but I wouldn't use it on a rusted part. In fact, I'm pretty sure that the only reason PB Blaster melts styrofoam is because it contains petrolium distillate (similar to gasoline). That doesn't mean its better than Liquid Wrench. The fact that PB Blaster would even try to advertise with this irrelevant "cup test" makes me not trust their product.

Understandable... but your loss. PB Blaster is the shiz. Maybe you could just soak your rusty nuts in water. :D (literally and figuratively speaking)
