Our take on the System Three Mirrorcast Clear Epoxy Casting Resin Kit

MirrorCast is a two-part clear epoxy made for filling knots, cracks and voids in wood slabs before finishing. It pours with minimal shrinkage, cures hard enough to sand, shape and drill, and can be tinted with System Three pigment dispersions. The 1.5-gallon kit yields about 345 cubic inches of mixed resin, so it suits medium to large fills rather than small touch-ups. Compared with thinner casting epoxies, it is built for deep void filling and wood art, but it needs a room at 70°F or warmer and gives roughly an hour of working time.
