I know repair shops that use dry ice to remove dents. They actually use a black light to find them first and, yes, they use dry ice to pop out dents. There's one place that did it to my sisters car after a hail storm.
I wouldn't know about the other thing.

Everything about doubling your mpg seems like it'd work. But I don't know about putting acetone in the tank. That sounds like it'd f^^^ something up. It'd probably burn up your fuel injectors or something. Maybe eat up the rubber stuff in/on the fuel line.

Yeah, it is. Apparently it helps with the ignition of gasoline or something. I would totally try it, but my luck I would f up and need a new engine. If gas hits $4.00 a gallon this summer, Im trying it though.
