Golden Paintworks® Metallic Paint Matting Additive is a concentrated dispersion of matting agents in an acrylic base that was formulated for use in all our Clear Glazes and Clear Topcoat products, but looks especially beautiful when added to the Pre-Mixed Metallic Paints. A recommended mixing ratio of 10 parts Metallic Paint to 1 part Matting Additive reduces the sheen considerably and leaves a soft, velvety look that goes well with any décor. Available in 8 oz. size
