Hi Rob, here's some info that could help you fix your tank. The tool I bought is called the "Twist-A-Dent/Ding King" and is sold through Target outlet stores. I think the cost was around $30. It has worked very well for me on steel tanks. They also have a technical support line for getting more glue sticks, as they don't recommend using regular glue. I can also bring it to a race if we're going to the same place.
