The Rupes White Finishing Foam Pad 100 mm (4 inch) is a soft, open celled foam finishing pad that is non-abrasive to the paint but firm enough to withstand the large stroke of the Rupes LHR75 3 Inch Pneumatic Random Orbital Polisher. Use this pad on the aforementioned polisher with Rupes Diamond Ultra Fine Gel Polish to burnish the paint to a mirror-like shine.
