How much paint?

Hey Brian. i just painted the engine bay of my car and took a pint of paint. So i figured out that it would take about 1/2 gallon of paint per coat for the rest of the car. A gallon of paint should give you almost 1 1/2 gallon once you mix in the thinner, (depending on how it is recommended to mix). Also with the paint depends on what you get (base coat/clear coat, v/s acrylic enamel, A/E will also have a hardner to go in paint. The best thing to do is ask your paint supplier.
