Joe's 4.5" Red Foam Applicator Pad is extremely soft yet durable. When applying wax or sealants, it is critical to not cause marring to your freshly polished finish. That’s why our closed cell red foam applicator pads are the right choice for even the most discriminating detailing enthusiast. Don’t take chances with other applicator pads that have pressed edges that can cause marring. These pads offers a “rolled edge” design allowing the safest and trouble free protection experience possible. These microscopic pockets within the foam’s structure allow your liquids to capsulate within the outer most layer greatly minimizing over saturation into the pad. This means that the liquids remain outside of the pad rather than getting absorbed into it equating to less product used. Soft yet stable design and 100% machine washable.
