Got a cheap brass finding you want to turn into dark matte iron? Or maybe silver polymer clay that you want to actually patina? Use a Swellegant metal coating!
Brush Swellegant Metal Coating(s) onto any surface. Let dry (5 - 15 minutes). Apply additional coats until piece is coated with no streaks or thin areas--usually 2 or 3 coats. (Note: for non-porous surfaces like polymer or glass, for best results you can use Swellegant Prep as a first coating.)
