I've been custom painting for 40 years, and the thought of shooting a whole car candy is scary to me! If you MUST...I would tell you to use one of the colored base coats, that is near the shade of the ornage, but the better advise would be to use what they call candy basecoats, and keep them well mixed while spraying.

Here is my BEST advise. Look at the new truck colors. They have some killer orange pearls, and they would bee MUCH easier to shoot successfully!

Candies are the coolest, but if you don't get them just right, it will look TERRIBLE!.....and touch ups are even WORSE! (You are going to drive it, right?)
