Ok before i hear any flaming or whatever, i just want to say that i read this off another site and want opinions to see if this would work or not. To simply put it, this only works on small dings like door dings and such. your suppose to heat up the dented spot first, apply DRY ice on it with gloves, and its suppose to pop out the dent. . . . i was always under the impression that heat expands metal and cold shrinks it back. i dunno, some people said it worked.... any comments?
