MeguiarÕs rotary soft backing plate is designed to be used with our 7Ó & 8Ó Soft Buffª rotary pads. The soft one-piece molded construction safely contours to curves and body lines resulting in a more forgiving polishing experience with less swirl marks. The quick hook & loop attachment system easily self-centers the rotary foam pads for excellent balance performance, while distributing even pressure for a smoother buffing application. Can be attached to all rotary polishers with a 5/8Ó diameter shaft.
