Optimum Microfiber Polishing Pad 5.25 in.OPTIMUM POLYMER TECHNOLOGIES. The 6.25 inch pad is great for compounding large panels efficiently, particular if you are doing an all-over paint restoration. The Optimum Microfiber Cutting Pad offers maximum conformability to the shape of the vehicle. The thick microfiber spreads cutting abrasives evenly over the curves and contours of the vehicle. The variable surface of a microfiber pad - compared to a flat pad - enables more compounding action with every pass of the polisher. To get an idea of how this works, if you rub your hand over a flat foam pad, the surface doesn't change. If you rub your hand over a microfiber pad, the microfibers move. The same thing happens when the pad is working against the paint. The pad is working harder, but you're not. Optimum Microfiber Cutting Pads are made with a new, advanced laminating system that ensures the pads will not separate or delaminate. This added durability enables you to use these pads with a rotary polisher. The semi-stiff yellow foam backing reduces heat and provides ample cushioning between the polisher and the paint. The foam backing is stiffer and thicker than the polishing pad to offer greater heat resistance. The foam gives the pad great flexibility. All Optimum Microfiber Cutting Pads are machine washable. Restore the shine to your vehicle with Optimum 6.25 Inch Microfiber Cutting Pads.
