Maximum Shine in the Quickest Time. This kit will allow you to bring many pitted metal surfaces to a high mirror shine in much less time than using regular buffing wheels and compounds. The 3M Trizact Bands (1 each of 5 grits) smooth rough surfaces more quickly and easily than other sanding bands because they feature a unique non-loading pyramid structure. They offer much more consistant cutting action and far outlast our regular abrasive bands. The soft rubber expander wheel yields to gentle contours to minimize edge cutting. The ventilated wheels cut faster. Also includes compounds and instructions.
