No. 555 Black Polish - 555 Black Polish-O-Ray

''''Good Old Five-Fifty-Five'''' as the boys call it. This is the ''''secret'''' that master polishers use to give that mirror finish to the gun after Polish-O-Ray(R) 500. For the brightest possible finishes, we recommend hard felt, followed by loose muslin for each grit as you progress through them. You can stop with any of the three grits when the desired level of finish is achieved. Suggest you experiment to find the combo and sequence you like best in your shop. The coarsest of the three, so you can move to the 555 family sooner. Great as a "Coloring" polish for aluminum after the final sanding steps. Follow with "Gray" on steel, skip to "White" on aluminum.
