Rupes Blue Coarse Foam Polishing Pad 80-100 mm (3-4 inch)
The blue 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.
