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. If an aged metal finish is desired, use Metal Effects. 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. Metallic Paint covers approximately 320-400 sq. ft./gallon.
