3M 7100119536 Wet or Dry Disc 8 Inch P500 Grit Ao

Product Description

The 3M 7100119536 is an aluminum oxide abrasive disc built on a waterproof mesh cloth backing that allows use wet or dry. The mesh construction helps prevent loading, which extends disc life and maintains cut consistency across sessions. At P500 grit, this disc is suited for fine finishing work where surface quality matters. It clips onto a hand pad or backup pad using standard clamps or clips, making it practical for hand-applied finishing passes. Licensed tradespeople and skilled finishers working in body shops, coating facilities, and fabrication environments will find this disc fits their standard workflow without modification.

This disc is designed for finishing applications on substrates including paint, e-coat primer, gel coat, and bare metal. The 8-inch diameter fits standard clip-on hand pads sold separately. The waterproof backing means it holds up under wet sanding conditions, making it suitable for both wet and dry passes on the same job without swapping discs. It is a single-use consumable intended for professional finishing environments where consistent scratch patterns at fine grits are required.
