Unique, Water Base, Non-Tarnishing Colors Real metal particles, pearlescent pigments and traditional color pigments are uniquely combined to create a palette of beautiful, non-tarnishing, shimmering colors. Colors in the Metallic Paint Collection contain three levels of coverage/hide: Opaque, Semi-Opaque and Sheer. Opaque colors have excellent hide; two coats are recommended for best results. Semi-Opaque colors have good hide; three coats are recommended for best results. Sheer colors are translucent overcoats that give luster to traditional paints, other Metallic Paint colors or faux and broken color finishes.
