Bought for testing the color my set. Am very pleasantly surprised at how strong the white color with low coverage lit on black fabric with black light. Would have thought that you need to apply thicker the paint. But it was not so. Class product! Note: in colors other than white should advance with white (not necessarily this black light white color, there goes also others) are "primed", otherwise you have too many layers of superimposed paint so that it lights up really strong!
