Not sure if this is true or works, but I read that for very minor dents if you apply dry ice it will remove them. I could see that this would shrink the metal slightly presumeably making the dent pop back into place. How you apply the dry ice and where you get it from I have no idea. Anyone tried this/got any thoughts???

I think you are using dry ice by applying with hammer!!

I can't totally imagine this working, but I can get dry ice and also have a small dent which I have been unable to push out from the inside - I might give it a go and let you know what happens!

Most F1 teams use it,why dont you go on the scrounge at silverstone.
why dont the fuking smilies work??????sarcasm doesnt seem right without them.
