Block sanding can be considered an art in itself and a little overwhelming. Most surfaces on a car are made of curves - a long major curve and a minor secondary curve. Once these curves are identified, then it's a matter of sanding at 45 degrees to each curve. The nature of a block will constantly take the average of the surface and only sand on the highest points until a perfect surface is achieved.
