Each aspect of the pad design has been carefully considered to deliver maximum performance, durability and results. Featuring a high-grip velcro backing for maximum adhesion and minimal pad slip, these pads will hold tighter to your machine reducing the chances of an errant pad or mid-polishing delamination in even the most extreme conditions. We listened to feedback and eliminated the neoprene mid-base section. Some users found it difficult to avoid putting rubber transfer marks onto the vehicle surface if the side of the pad was accidentally bumped against a panel, which could cause a scare and be somewhat difficult to remove. The convoluted face generates less heat and the tapered edge design provides stability that can withstand the rigors of today's large orbit and forced rotation polishing machines. To aid with cooling, plus reduce weight, each pad has a precision cut center hole that can also be used to aid in centering the pad on the backing plate.
