a pint? youre going to need a hell of a lot more than that. i think when i painted my soap box car it was like several pints, but that was long ago.
enamel -- its like the cheapest way to go, it was a shot.
the most expensive of course is a urethane base coat/clear coat, which i think is some sort of lacquer...but im not real "up" on my paint trivia. its something i can do if i have to, and i know its expensive. im pretty sure materials for a car should cost from a body shop like $150-$300 just depending on the colour/paint type.
