MMP Paint is a premium non-solvent organic pigment, water-based paint product. We do not use plastics or large grain pigments, and are designed for spraying in all airbrushes. Mission Models Paints are non-toxic, odorless and safe on all surfaces and materials. We recommend thinning with MMP Thinner for best results. In addition, add MMP Polyurethane Mix Additive to your thinned paint for improved durability, leveling and sanding qualities. Due to the nature of our MMP formula, tip dry is greatly reduced compared to other plastic-based hobby paints, and we recommend spraying between 15 and 20 psi, (with lower psi for fine lines). Spraying Mission Models Paints in thin coats gives the best results and will not hide the finest of details -- the thinner the coat, the better the results. With proper prep our paints can be used on all surfaces, and using our MMP Primer is recommended for best performance and adhesion. MMP paints can be sprayed over all other primers and paint finishes, and are also designed for superior blending and custom mixing. Once cured, our paint will accept all clear coats. Exceptional brush painting can be achieved straight from the bottle, or thin as required to suit your needs. Figure painters can add a drop of MMP Polyurethane Mix Additive to slow drying and blending times.
