paid 50 bucks for the roll on kit with everything included originally. and the gallon or whatever size the big cans are, went a long ways. it was enough to do the bed and rockers with no problem.
also, it saved my *** the other night. it was really windy and I was working. well i guess a cart was left out and the wind caught it and shot it into my truck. not even a dent, just a red smudge from the plastic on the cart that can easily be touched up
