Mission Models Paint is U.S manufactured. A large range of colours in waterbased acrylic. They can be both brushed and airbrushed. When airbrushing please follow the manufacturers recommendation on thinning and polyurethane additives, they do work. Using other products to thin MMP or thinning the paint to a different ratio often results in paint problems. Polyurethane is not recommended for Primer. You will find metallics at the bottom of this list and also on the Mission Models  thinner/primer page.
