SDO Black Finishing Polishing Pad 5.5 x 7/8Standard Duty Orbital (SDO) pads are designed to offer the same great foams as the HDO line without the dual-layer construction and are suitable for all random orbital DA polishers with a center ventilated backing plate. The center hole provides a tunnel to release and dissipate heat from the foam, reducing surface temperatures, making it less likely to damage the paint.Consistent performance, firmness throughout the heat cycle, and user experience. Foams provide maximum durability and consistency when polishing with a long-throw polisher.Benefits: Finish - Black foam pads are used for final refinement, jeweling very light swirls on soft paint. Use with extra fine finishing polish. The black foam works to refine your corrected surface to a flawless gloss, removing any trace of cutting haze from the correction stage(s) above. On very soft paints, the black foam could also work as a one-step process to remove very light swirls and finish perfectly in one go. Tapered Edge Prevents pad rolling and provides great pad rotation. Great for curved and contoured panels. Allows for precision polishing in tight areas. Center Ventilated Cooling Chamber Dissipates heat away from the center of the pad, reducing temperatures and increasing durability. The system also allows for perfect pad alignment. Designed Together The SDO system pairs perfectly with our low lint wool heavy cutting pads made of knitted prewashed lambswool.
