With traditional buffers you would have to screw in each pad with a wrench or deal with bonnets. This backing plate is designed to screw right into the Porter Cable 7424XP Random Orbital Buffer, Griot's Garage Random Orbital Polisher 6" 3rd Generation, Meguiar's Dual Action Polisher G110v2, etc. so you can easily swap out your favorite pads. After the backing plate is screwed on it stays firmly attached and the hook and loop pads lock in place. The backing plate is semi-flexible which allows you to work on curves and tough to reach areas. With firm and constant pressure you can breakdown each product and work them in to the surface properly. Now your polishes will give you a deeper shine and waxes will adhere to the paint longer. Check out the various sizes of this backing plate offered and the pad recommendations for each size below! The Dual-Action (DA) Backing Plate will save you time and effort as you achieve better detailing results!
