Amazing GOOP® SuperMend® is an all-purpose, off-white, two-part adhesive putty that bonds permanently to most substrates. This super-strong epoxy fills holes, cracks, gaps and dents of any size or depth - without shrinking or popping out. SuperMend® is impervious to water, gasoline, diesel fuel, motor oils, transmission and hydraulic fluids, anti-freeze and most chemicals. Once cured, SuperMend® can be sanded, ground, drilled, tapped or sawed. It will accept self tapping screws and can be painted with most paints.
