A google search returned one hit on FABO..... About how much paint to do three coats on a B body engine compartment? This is my first time painting anything this big. Kind of intimidated. Ready to do it , though. All blasted, primed, masked. I bought a gallon of single stage thinking I'd eventually do the whole car minus the engine compartment, so I don't want to waste any by mixing too much. Mix is 8-1-2, so I'll end up with almost 1.3-1.4 gallons, right?
