Jacquard developed these specifically for airbrush applications. They are available in Transparent, Fluorescent (glow under blacklight!), Opaque and Metallic colors, all of which are water based and intermixable. The colors will work on almost anything, including some fabrics, leather, wood, plastic, and metal. For use on non-porous surfaces, some light sanding may be required, and bare metal may need a base coat of primer. Heat setting with a heat-gun or dry iron is recommended for permanency, or mix in some Jacquard Airfix right before use and cure a few days. These are fantastic for customizing sneakers! Marblers please note: While most of these colors will work just fine for marbling, and used to be the best we had for that, Jacquard has released Marbling Colors specifically for that purpose which are practically foolproof for marbling! These deep, brilliant colors airbrush like a dream on any surface including fabric, leather (including shoes!), wood, plastic and metal. Jacquard colors are bright, clear, inter-mixable, and acid free. Once dry and properly heat set on fabric, Jacquard Airbrush paint is permanent and indelible in water.
