Spaz Stix Solid White is an opaque color that can be used as a primary color in your paint scheme, and is specifically formulated to perform perfectly as the required backer for the Spaz Stix "Fluorescent" line of paints. It can also be used to back the "Candy" colors to produce the lightest, brightest combination possible.
All Spaz Stix paints are formulated for use on polycarbonate material. Specifically, clear bodies for R/C cars and trucks. Be sure to test compatibility when using on other surfaces.
