The RUPES Blue pad is designed with large cells to dissipate heat quickly allowing the compound to effectively remove heavy defects without the side affects of overheating with some foam pads.
When used correctly RUPES foam pads are designed to effectively recycle the polish across the face of the pad rather than allowing it to be absorbed.
Additionally, all RUPES foam pads are designed with a center hole to alleviate the high stress/low functionality at the center of any foam pad avoiding collapse of the structural integrity of the foam.
