I tried it once on a kawasaki tank. It was a very small indentation. Searched the internet and found several ways to do it but nothing worked. I covered the dent with dry ice until the tank was frosted then put a heat gun on it but no go. Another way I read was to heat the dent first then sray an inverted computer duster on it to make it pop. Don't know if this works. After trying to fix the dent I realized the inside was badly rusted. I also had a bad dent in the front fender of my harley. The lone 2x4 in my shed decided to jump on the bike and made a sharp 3" crease in the fender,not breaking the paint. A local dent doctor got the dent out. It was amazing the job he did. Would never know there was ever a dent.
