Wondering if any of you folks have tried doing some paintless dent removal. I've seen two methods illustrated out there on the 'net, one using canned air and a lighter (or hair dryer) the other using dry ice. I'm going to give a try with the air/dryer method today since I don't have a source for dry ice locally. Just thought I'd ask beforehand if any of you have had experience with either of these methods, and if so, what I should look out for.

I'll post photos when I'm done.

the idea is that the metal will expand and then contract (if using heat) and shrink the dent, although i'm not sure if a hair drier will be enough to do it. the dry ice idea is that you will simply cause the metal to shrink. in either case, i'm not sure how good the result will be and i doubt that it will be 100% better.

I have messed around with using a torch to try and shrink dents in sheet metal back when i was in the highschool auto body class a few years back. One thing I have to say about that is that it is possible to shrink dents using that method, but it is also easy to warp large areas of sheet metal when trying to do this. As thin as the metal is on newer cars, it is probably best not to try using heat to shrink the metal.

There is also another method that body shops like to use in which they have an overhead projector cast a bunch of lines across the dents and they will use spoon like prybars to push up from the back side of the panel to raise the dent until the lines are straight.

Don't waste your time or money on dry ice. I've tried it and it was a miserable failure
