Tank dent removal

When I was around 16 and learning to ride my XS650 I put more than a couple dents in the the 'ol tank. So I figured I could make it pretty again with a little charge from the air compressor. Imagine my surprise when the tank not only kept it's dents but aqcuired a "bowlegged" stance when the compressed air snapped the sides of the tank out a couple inches. Nice!

It's an old bike - just ride it.

Here's a dent removal method from the kz650.info forums

Stud welders are great, but pennies are much cheaper.
Braze some 1 or 2 inch pieces brazing rod to the middles of some pennies. Then grind the faces of the pennies smooth, then solder them to bottoms of the dents on the tank. Then grab hold of the brazing rod stems with a slide hammer and tap the dents out. Of course this method, like the stud welder method, requires a new paint job.
