Candy Paint???

Where is the cheapest place to get some House of Kolor Candy Paint, and if anyone knows, how many cans do you think it would take for my hatch.

what color is the hatch korn ? and if it is fully primered what color primer is it ? and if it is fully primered are you gonna use a tinted primer sealer ? and what color paint are you looking for ? and were you tryin to do a 3 stage base coat and multiple clears or ... ? its alot of questions i know man but it does make a diff on how much you need..altho i would say 2qt -1gal but it all depends. Im not overly to sure of the cheapest place to score kolor, I get mine around town so I dont know of anywhere else ..i guess its just beacuse im Lazy lol
