Well it depends on if your doing the inners aswell as the outside. To do the outside i would say atleast 5 pints of the mistichrome. and that does not include the black base that you apply underneath the mistichrome. You will need about 3-4 pints of black, I would buy 4 to be on the safe side. Its always better to have more than less cause if you run out while painting this stuff its not good. unless someone has it in the store close to you. Hope this helps.
