8 Bit Baits has some really outstanding additives for both plastic and airbrushing. Right now, I have 6 of their holoshift pigments and plan to get more, specifically the Pixie Dust. I don't have any pictures yet but will soon. The holoshift colors I have are all white particle, making them virtually invisible in plastic and paint but the colors that come out when applied over black of other dark color is impressive. On the site's holoshift page all of the colors are shown mixed IN ia thin smoke. OVER black mixed in a clear plastic topcoat or clear paint they're eye popping.
From what I gather in reading up on the different product offered, they are all heat tolerant which makes them good for plastic injection. They seem sort of pricy but based on what I have used, a little goes on heck of a long way, especially in airbrush paint.
These products can be seen by searching 8 bit baits, using the number 8.
