Eastwood used to sell a prism additive for powdercoat, you can try paint with pearl for some funky stuff

I agree with "Paint". Xirallic flake is the large flake in most new car colors that make the pearl colors have the large flake and have that cool pop. All paint companies have these in different colors to match the OEM colors, so you can mix up what ever you want. Some have powder ones and some have liquid. Just use the same brand as the paint you are going to use. And do a bunch of sprayouts to see how many coats you need. Also walk the car if you are doing the whole thing or your edges will be darker.

 

Oldtimers will tell you that back in the day when it was known as Murano pearl, this was actual crushed colored glass from the premier glassblowing epicenter of the world - the Island of Murano in the Venetian Lagoon, suspended in lead salt. The latter component explains why it has been banned for many years....
