Santini mixed three different sizes of flake together in the clear to get the desired effect. The small flake fills the gaps, and the large flake adds the drama. Each coat should be allowed to get tacky before another is applied. A good way to test readiness is to dab the paint on a taped area with your finger. If it is sticky but does not create a string when you pull your hand away, it is ready. Keep adding coats until everything is covered evenly, usually about three to four coats.
