at least a gallon of base to be sure and min. gallon of clear.

I used 2 gallons of single stage, a pint of hardner and a gallon of reducer on dad's short bed, did underhood, minus inners fender wells, inside cab, floor and all, doors and jambs, and inside bed but barely. Truck body got a good 4-5 coats.
