Yeah, indeed it does add up but consider I can paint up to 2,000gp worth items which are either made from cheap material (or same material which upon paint was painted) then it can be easily paid back if I happen paint skillfuly say a statue of one of you guys atop a gold plate. Gold may be up to 1,000 but it can rise up to ten times the cost if it's skillfully made statue.<br/><br/>So can buy more pots of said magic paint stuff once we go below 500 cubic feet :).
