3M Perfect-It Double Sided Ultrafine Foam Polishing Pads were developed specifically for ultra fine polishing with 3M's Ultrafine Machine Polish. The pad utilizes 3M's patented convoluted foam design to provide smoother handling with less splatter. Additionally this pad features two polishing sides and a central attachment that allows more work to be done with fewer pads, in less time! The 8 Inch Ultrafine Double Sided Foam Polishing Pads are made from an extremely fine open cell polishing foam that removes fine swirl marks without creating any. 3M Perfect-It Double Sided Ultrafine Foam Polishing Pads feature a perfectly centered female attachment to attach to the 3M Quick Release Adapter for easy changing.
