Straightening a large panel requires a block that will not follow every low spot. The Motor Guard BGR12-1 Big-Block provides a rigid, extended sanding surface for aggressive two-handed blocking across broad repair areas.
Its 11-inch length helps bridge surface irregularities when shaping filler and leveling primer. The PSA face works with 2-3/4-inch sticky-back abrasive rolls or standard abrasive sheets, allowing full sheets to be used efficiently.
