The construction and beveled, flat face of these pads promote even application of product, more consistent results, and easier wipe off. We select premium, reticulated, open-cell foam for all our pads because it increases durability and improves tear resistance. Flip one over and you'll see our improved micro hook-and-loop system that offers improved attachment and quick detachment. We also employ a thermoset bonding that's durable enough to make our foam pads machine washable propositions. 5" and 6" pad sizes feature a center intercooling hole designed to resist common heat buildup on the pad face, eliminating pad dishing, extending pad life. For use by hand or random orbital.
