RCP's 6" J-hook 658y Backing Plate is a rigid yet flexible backing plate built for rotary polishers, making it an essential component for paint correction and polishing on larger panels. Featuring 5/8"-11 threads in a female configuration, it threads directly onto your rotary polisher's spindle for a secure, reliable connection during cutting, polishing, and finishing work. Its hook-and-loop face holds 6-inch pads firmly in place while the balanced rigid-and-flexible design helps maintain even pad contact and absorb vibration for smoother results. Built to handle the demands and heat of rotary correction work, it keeps your pads tracking true panel after panel. Paired with your rotary polisher, quality compounds, and the right cutting and finishing pads, this backing plate takes your paint correction to the next level.
