Oooooh no, don't use the Ding King or any similar do-it-yourself dent removal system. I tried to remove a dent myself with it from my old car and it did come out, but the metal was full of ripples. I would strongly advise you have it professionally removed. Google "Dent Wizard." Sorry, don't mean to rain on your parade pzr2874, but I'm speaking from personal experience here. My WRX was recently hit by a shopping cart that rolled down a big hill and I had a dent in my rear quarter panel right by the gas cap. From a personal recommendation, I looked up Dent Wizard and found out they travel around and were at a dealership less than a mile from my house for a couple hours that very day. I took my car there as soon as they started working and they gave me an estimate and used their paintless dent removal system while I waited and I swear it looks like there was never any damage at all. It's absolutely perfect. It's not horribly expensive either, expect to pay (very rough estimate) around 100-200 depending on the size of the dent. I swear by their work and I'd recommend them to anybody.
