Happy to Matt
1. Fly your hail dented plane to West Texas. (MDD in the summer time is best)
2. Park on ramp around noon.
3. Go eat Mexican food.
4. Stop by grocery store and buy dry ice.
5. Using the welding gloves and tongs that you brought along extract a piece of dry ice form the container.
6. Place the dry ice on a dent (in the well warmed aircraft skin).
7. Enjoy the "frying" sound of the dry ice.
8. After 15 to 20 seconds mode the dry ice to another dented area.
9. After a few hours of work in the pleasant, warm West Texas sun Bob's your uncle! (I've waited a long time to use that line

) All but the worst dents are gone - please don't ask me where they go.
