Abstract: A kit includes a collection of sanding blocks of various dimension and geometric shape for use in fine sanding exterior surfaces of an automobile body or marine craft during a body painting process. Each block is provided with one or more pressure application areas which are uniquely configured for sanding a particular surface contour in a manner which maintains uniform contact between the surface and a fine grade sandpaper overlying the pressure application area of the block. Use of the various blocks in the kit enables even sanding of all surface areas, including difficult to reach areas, without damaging the painted surface.
