I'm not sure. I have a workmate that said he managed to get some smaller hail stone pitting out of his car by leaving it in the sun to get hot, then placing an ice-cube in the centre of the dent to pop them out. Same principle so may work on smaller dents.

I had a dent on the door of my old Bora after some idiot misjudged the front of their car bumper when turning out of the driveway. I used the CO2 trick but it only removed part of the dent. When I took it to a smash repair place they said the metal sheet of the door had actually been stretched so a paintless repair wasn't possible. So presumably (without being an expert at this at all I might add) as long as it's a shallow dent that has not stretched the metal and doesn't have a crease in the sheet metal, your chances of this method working are decent. At a minimum it's probably worth trying, and if it doesn't work then get someone that knows what they're doing to sort it out.
