Long description:
These familiar reddish-brown colored "bricks" of compound are most widely used for cutting down and bringing out high luster on non-ferrous metals. Fast cutting and bright coloring action makes these compounds the best choice for buffing all types of zinc die castings, copper plated work and aluminum castings and stampings. A greasy grade is generally selected for coarse work because the extra percentage of grease binders keep the compound on the buff face longer increasing the cutting action. Lighter, drier grades are used for cut and color operations or for light coloring before electroplating. These compounds are practical with any type of buffing wheel, but generally used on a tight, spiral sewed, pocket or bias type buff.
