Our Fluorescent and Glow paint lines are specifically designed with night time RC addicts in mind! The Glow paints harness solar energy for a brilliant glow in even the darkest of night time conditions. There are 2 types of Glow in the Dark paints, which is why they're priced differently, the 'Radioactive' range costing a little more due to the higher concerntration of glow pigment contained in them. The paints marked 'clear' are 95% clear, and in most cases you can apply the paint onto the surface and it just looks slightly clouded, you can then apply a backing colour behind it which you'd see in daylight, while at night when charged the body would glow the colour you applied. The other paints all have a visable colour to them, and ideally would be best backed with either white or the same colour (ie back #20600 Yellow with a standard yellow). In most cases the glow results are more visable when backed with white, darker colours make the results harder to see.
