The blue foam pad is designated by Rupes as being a hard cutting pad. It is a large-pore, thick-wall design. This pad initially feels very rigid, but becomes more pliable and comfortable to use as the pad warms and saturates with buffing liquid. The wide open-cell design of this pad keeps it clog-free longer than traditional foam cutting pads, but it may sling a bit if too much compound is used. To control slinging, do not oversaturate or use an excess amount of compound with this pad.
Designed for use with the Rupes machine polisher but suitable for all Dual Action polishers with a 6″ (150mm) backing plate
