Fine Finish adds a strong sandable and wet-sandable surface to EVA foam. It’s a nontoxic brush-on acrylic-based filler, and contains very fine sized particles for professional results. It’s designed to brush on flat to reduce sanding time. Bonds well, dries fairly quickly, is flexible, and is very easy to sand. For best results use Rapid Fill first before applying Fine Finish. For best results for wet-sanding, 3 to 4 coats are needed. Comes in white and dark gray.
