The 7940 Siaair 3" velvet foam disc is built from three layers: a net-backed abrasive on the outside, foam cushioning in the middle that equalizes pressure to prevent over-sanding, and the proven siafast hook & loop grip on the inside. It conforms to contours, curves, and edges for a flawless finish in both wet and dry sanding. Waterproof, washable, and resistant to silicone remover for repeated use. Compatible with standard 3" backing pads.
