The SONAX Yellow Dual Action Polishing Pad is used to finely perfect the paint after compounding, or if your paint just needs a medium polish. The hole in the center of the pad provides good ventilation while in use and prevents both your pad and the backing plate from overheating. The white hook & loop backing is firmly secured to the foam face, and will not rip or tear during use. Use the SONAX Yellow Dual Action Polishing Pad with SONAX Perfect Finish to achieve a clear, shining finish. SONAX Yellow Dual Action Polishing Pad measures 5.5 inches and can be used with a 5 inch backing plate.
