Abstract
Abstract A power operated device for abrading surfaces, which device is particularly adaptable for use in the repair of vehicle bodies, wherein epoxy material is used to fill body dents and irregularities. The device may be adjusted to abrade the surface of the repair material without marring the finish of the surrounding area, and the surface of the abraded material is so abraded as to have the exact contour as the surface originally had, whether the surface is concave, convex or planar.
