That kayak really isn't paint its actual glitter that is thrown into the first layer of clear resin when the hull is glassed up, unfortunately.

We used the same trick with clear polycarbonate slot car and rc car bodies. After the glitter is tossed into the clearcoat (actually, a matching transparent clear coat or tint coat works best) and hardens, the solid color is then put on top of that. When they pop the part from the mold that is what you're seeing, all done in reverse kinda from the inside.

If you are looking for a glitter paint job rather than a metallic flake paint job (to help define the two) be prepared to go thick with the clear coat and a lot of leveling sanding between coats, because a glitter job leaves it pretty rough and you have to fill past its height before you can start to smooth it out with lots of clear.

I did a quick search on glitter paint jobs and came up with [link=http://findarticles.com/p/articles/mi_qa3825/is_200309/ai_n9295823/]this.[/link]

It describes how to do clear bodies but you'll pick some things up from it.

I often wondered how to do a heavy glitter job the best way over wood and still studying that.
