If it was that simple all of us would of heard this along time ago....how could putting dry ice on a dent pop it right out?
Think about it, cold causes expansion. The surrounding area of the dent is subjected to extreme cold, which causes the metal to expand, thus pulling dent with it. BUT, and I repeat, BUT, its only really effective on thin, soft metals. Like aluminum.

That sounds like the slosest thing to a rational explaination I've ever heard on the topic!
If it really worked, wouldn't everyone know about it? Wouldn't dent repair men use that instead of pulling interior panels and using body spoons and such?

It works but:
The dents must be small. Big dents or dents on funny body bends or near the edges don't work. Hail pings are the best candidates. Dents must be fairly recent. And yes dry ice is some what expensive so there must be enough dents to warrant the expense. So basically small multiple dents like hail damage would be the best scenario.

how does that make any difference?
I think CYMFC3s is the only one who makes any sense on the subject.

Ok, i lied and made the whole thing up.

Last Time I checked when metal is cooled in contracts. It expands when it is heated.

this does work, but its best to lightly push out (LIGHTLY) from the inside after and while you've got it very cold. A dent is basically an expansion of the metal, so the ice coerces it to contract. With a little pressure (if the dent is small enough), it comes out.
This has worked on three cars, a 3000gt (about 5 dents.) and two each on two fd's. (fenders)
