Where to get or make iridescent lava for a grande?

[lavalover]

I was on eBay recently and saw a grande that someone rewaxed with silver metallic lava which was kind of cool. I can’t find it now but I know that recently I was looking around and saw a grande that was redone in an iridescent oil slick color. Does anyone know who makes the kits for those kinds of colors or finishes? Thanks

I noticed that the blue dye from the lava louie goo kits results in a somewhat iridescent layer on the wax. Will have to see if I still have the bottle which had this "feature". If so, I'll upload a picture of it and let you know.
