The candy is a translucent color coat, which is either a specialty candy paint or a clear-coat paint tinted with dye.
The final color and darkness of the finish depends on the color and darkness of the basecoat, the amount of tint in the candy coat, and the number of candy coats applied.
Candy paint requires a lot of sanding and is very labor intensive. It also requires a skilled painter to get a consistent color, as any variation in the thickness of the candy paint will appear as streaks or dark/light patches in the final finish. Due to this, candy paint is usually very expensive.
