Man, I thought the sixtie's were SO over! Coming back to glo-paint, are we? The actual glows byitself stuff is kinda lame, but if you had done a search on this forum topic you would already know that. Talked to death about three months ago. If you want something that gets active under blacklights, ANY of the neon-bright paints (DayGlo) will phos quite well. If you want to use it as a grain filler so it is there all the time, remember how awful the stuff looks in regular light. Pick a color and see if it is available as a phosphorescent ID oil from one of the security supply companies. If I remember right, you can only get lame red, orange, green and a neon blue. Only works under blacklight, however.
