What you're basically doing with candy colors is shooting a metallic base coat, and then shooting tinted transparent coats over the base. I shot a few cars in my day, but never a candy paint job.

The body shop guys I knew said they were very hard to get right. And that was with top notch spray gear. With a Preval sprayer you will probably find this hard to do. But the only way to learn is to try it, right?

I was able to find small volumes of HOK paints available thru Amazon. You could order a small quantity and get some practice on some cheap hardware store pipe before attempting to do a frame.

There are all kinds of resources online to research applications of candy paint. Here's one I found:

Candy Apple Red

Good luck!
