Wicked Fluorescent Colors are water-based, multi-surface airbrush acrylics designed for versatility with optimum performance on nearly any project. Heavily saturated with transparent pigments, Wicked Fluorescent Colors use a durable resin suitable for interior or exterior applications. For maximum color brightness, apply over a white base, such as AutoBorne Sealer 6001 White. As they are NOT Lightfast, fluorescent pigments will eventually fade due to exposure to direct light.
