Get a cup of coffee and watch the frost evaporate and watch for the "POP" . Contraction and rapped expansion within the medal has the potential to "POP" the dent back in place. There's "technical" video's on YOUTUBE on using this method.

Neat stuff, thanks! I have both at home, it's worth a try.
Still waiting on feedback from my local Nissan dealer. And they get pissy when I don't respond to them ASAP... hah!
