Sorry for your pain, when it happened to me it's all I could see for weeks.
I had a very Sharp ding in my door a while back, right in the middle, there a post on here somewhere.
Took it to a local (at the time) dent guy (painless removal etc) he had to use an electric current to soften the metal to get it out. Luckily for me it somehow hadn't taken the paint off so it was salvageable.
He did a great job but in certain lights I could still see a warped area as I was looking for it but to someone who was unaware, they wouldn't notice it
