Colors have a delayed curing cycle (soft erase) during which colors erase easily and after 48 hours cure to a hard matte finish. Illustration Colors are intended to be used directly from the bottle but can be thinned with 4011, 4012 or 4013 Reducers. For hard-surface application, mix 4030 Balancing Clear with Illustration Colors for an excellent transparent color.
Auto Air Colors do not offer the soft erase feature that the Illustration Colors offer. These are the pioneer brand of water-based custom colors and airbrush paints. Prover durable and brilliant, these are very thin, high intensity metallic colors intended to be sprayed from the bottle.
