3M Perfect-It Foam Compounding Pads are 3M's highest-performing foam compounding pads for refining sand scratches, slow-speed polishing, de-nibbing and more. Foam face pattern provides more surface contact, holds compound better and reduces slinging. Doubled-sided pads work with 3M Quick Connect Adaptors on rotary polishers; single-side pads work with the Hook-it system for easy change-outs.
