#metalpolishing #metalpolisher #detailinglife #trucking #bigrig how do you polish aluminum to a mirror finish? Previously this aluminum truck grill was sanded to a 600 grit with a DA sander. Our savage 600 grit ceramic long life sanding discs were used. This cut buff stage involves the use of our T88 cut and color metal polishing Tripoli in combination with a stiff orange mil treated airway buffing wheel that is being run at 3500 RPM @Clean Culture MDS #CapCut
