Used by professional Cosmic Star Ceiling Artists for highlighting and Star Ceilings. This versatile Glow in the Dark paint is made from the purest product available and has a glow life span of over 10 years. What makes this paint glow brightly is our crystal formation, just like small batteries they charge and discharge their energy. UV rays from Sunlight or even Black Light UV will supercharge this paint, incandescent and LED takes a little longer. All ProFX paints are structurally designed to be thinned down for use with airbrushes. Do not mix any acrylic paint with water as this dulls the polymer of the medium, making a virtually clear paint opaque. We do sell our airbrush and thinning medium through our Amazon store.
