Ultimate Extreme White glows Aqua Glow in the Dark Professional Grade Acrylic paint. This paint was initially designed to be used by Professional Star Ceiling Artists to create virtually invisible painted ceilings. Goes on semi smooth and, virtually invisible on light surfaces. Non-Toxic, Flame Retardant, Dries Waterproof. For optimum color, glow and brightness we would suggest investing in a TRUE 365nm Black Light bulb. Although these are expensive, they really make the paint pop. Our paints can also be charged with direct sunlight for hours of glow! On White or OFF white surfaces, they are virtually " invisible".
