CarPro Wool Cutting Pad has been redesigned with an even more durable and dense foam interlayer. It fits a 5″ backing plate just right and tapers out to a 6″ polishing face! It still utilizes the excellent short hair Japanese style wool design with a self centering hole to easily balance the pad while also aiding in a cooler pad and polishing surface while in use. Anyone who has studied their polishing pads after heavy use has found the center of the pad is nearly useless. By removing this portion of the pad we allow the surface to stay cooler while also providing a self centering hole to save time during pad mounting. This pad not only provides heavy cut but finishes down incredibly well for a heavy cut pad.
