How much paint to buy?

For show you'll need the engine bay and door jams the same color as the exterior. :o
and you should need about 5 qts for the color coats.

Yeah, I knew I needed the jams the same color. And after thinking about having an engine bay that didn't match I decided against it. And I actually asked another guy I know about paint and he said about 5 quarts as well, so I think that is what I am going to get. How much clear coat should I get? I would like to do four coats of clear. Will 6 quarts do four coats, or will I have to get more? Thanks for the help, guys.
