The 3M Perfect-It ll wool compounding pad refines sand scratches and other paint surface defects. This single sided, 5-1/4 in wool pad is designed for use with 3M Finesse-it polishes. It attaches to a rotary buffer with the 3M Hookit attachment system for fast, easy changeover and reattachment. The 3M Perfect-It II wool compounding pad is made from 100% fine wool fibers stitched onto a durable polyester backing. The dense 0.68 in H pile distributes and applies material evenly and consistently, refining scratches and paint surface defects. More aggressive than foam pad, wool dissipates heat far better, leaving working surfaces cooler. The pad's natural fibers are tapered, don't splatter applied materials and leave fewer scratch marks. This pad is prewashed to reduce lint. The Hookit hook and loop attachment system makes attaching, removing and reattaching to your rotary buffer simple and provides a secure connection even in heavy duty applications. Used with Finesse-it polishes, this wool compounding pad is just one of 3M's portfolio of products that, used in combination as prescribed, optimize your results to leave the most perfect finish possible. The Perfect-It brand means this is 3M's highest performing single sided wool compounding pad. And, as with all 3M products, it's manufactured for consistency and quality, to provide optimal results within the 3M Perfect-It system.
