Montana Night Glow is a high-grade acrylic spray paint that contains luminescent pigments that absorb and store light particles, then emit glowing-light in darkness. The intensity and length of the glow depends on the thickness of paint. Apply multiple layers of Night Glow over a well-primed white surface. It is suitable for all smooth, rough or light primed surfaces such as metal, wood, plastics, primed cardboard, walls and more. It has limited resistance to weathering, light and UV-influences. Use with Montana Fat caps. 400ML Spray can.
