3M Synthetic Steel Wool Pads #2 Medium - A combination of synthetic fibers and abrasive particles that work like steel wool. Yet these durable pads are easier on hands, resist clogging, and can be rinsed and reused. This pad won't rust, splinter or shred. Will outlast steel wool. 3M Synthetic Steel Wool Pads are compatible with both traditional solvent-based and newer, water-based strippers and finishes.
