I will start by saying........if you are a rookie painter, you DO NOT want to start your first paint job in candy!!!.
Candy is the hardest paint to lay on correctly. If you do not have experience especially in HOK candy you can "tigerstripe" the paint, run it and lots of other things that can happen. I have been doing custom paint work off and on for 30+ yrs. And I won't attempt candy because I have not done enough candy paint jobs to be good at it. If you make a mistake with candy, you must start all over again, there is no fixing it.
If you practice with other paints, you can use HOK pearl. The pearls are more forgiving. There are many videos and books out there to help point you in the right direction but the main thing is to get experience and practice, pratice,practice.
