Base coat of Silver recommended.
Mix Candy into clear coat to give the depth of color you want. Spray light passes to build up color saturation.
Mix ratio will depend on how much color you want.
Recommend starting with (by volume) .5ml to 18ml of clear until you reach the color transparency you desire.
For more depth of color add a gloss clear coat over.
