First you heat the dent up with a lighter and foil in-between the fire and paint so as not to scorch the paint, then after it gets hot you hit the dent with the compressed air, voila....dent pops out.

Seriously??? So if I use a heat gun to warm the steel, then shoot it with liquid CO2, the dent will pop? Seems kind of counterintuitive (6) and like it may POP the paint, but I'll try it....
