Paint that glows in the dark for up to 2 hours! Paint wood, walls, metal, masonry, lots of stuff.
Keep in mind that you need a light source to properly "charge" the paint or to make it glow for a while. If you paint something that doesn't get a lot of light, this jsut ain't gonna work.
Also, it works best on highly contrasting colors - dark or light bases are best. For instance painting a beige wall doesn't work very well, but painting a black wall will work pretty good.
You might need a couple of coats for best results.
This would be pretty cool in a garden, outdoor party area, walkway, etc.
