Have your polishing setup equipped with the Blue Treated Airway Buff, designed for cutting and finishing applications. Available in 6-inch and 8-inch diameters, these blue treated airway buffs feature 5/8-inch and 1/2-inch arbor compatibility. The 6-inch version has 12 plies and is resin treated for extra heavy-duty cutting and polishing, while the 8-inch version has 16 plies and is designed for cutting and finishing. Both options feature biased-cut cloth and a folded design intended to provide a balanced working surface. Each buff is sold individually and is listed as a high-quality aftermarket replacement part, not an OEM component. These universal polishing accessories are suitable for compatible heavy-duty truck applications. Verify the required buff diameter and arbor size before ordering to help ensure compatibility with your equipment. This is a special-order item and is non-cancelable and non-returnable.
