crazy it depends how they did it. using the koncentrate is one way of doing it or u can just get the kandy already mixed by the gallons. if u are going to use a lighter color get the already mixed because if they dont mix it just right candy is very tempermental and you will be able to tell a difference if the color is off. but i would use the hok clear only, they have some very good shit, spend the extra to get the hard shit, not sure what the code was... using ppg could have effects with the chemicals inside them not interacting. also if hok determines that something in the paints is defective they can do recalls and send you all new paint, wpnt happen if you use anything else. and when u are spending that kind of cash im not taking my chances. good choice that u did crazy, just in case....
