Sold individually, buy only the contrasting colors you need. Ghost Glow is a light-activated paint that will glow in the dark for approximately 2 to 3 hours after being exposed to a bright light for 2 to 3 minutes. In an emergency, you don't have time to think about aiming. Be accurate, nothing contrasts better. These high visibility paints are really plastic and have the ability to expand and contract with the gun metal - no more chipping, cracking or flaking off and you don't have to repaint your sights every time you leave the range! After you've cleaned the area to be painted with mineral spirits, the best applicator is a wooden toothpick. Keep the cap on tight, it will last almost forever. Ghost Glow is available in yellow, white, green and orange, $7.95. Bright Sights comes in white,yellow, red, green and orange, $5.95. Free S&H on any single item ordered with a SmartCarry® holster.
