How much will a ceramic engine paint cover?

i was thinking of using this a href="http://www.eastwood.com/ew-ceramic-engine-paint-quart-hemi-ornge.html" rel="nofollow"http://www.eastwood.com/ew-ceramic-engin…/a paint to repaint the engine in my charger. i was also going to hit the engine bay. assuming i use a 4-1 paint to hardener ratio and i spray through a HVLP gun how much should i get?
