See-Thru Cushion Pads 3" and 4" — Bumpon, Medium-Flex and Soft-Flex

Mount these Cushion Pads onto your Backpads for a smoother grind and more gentle polish. Recommended for use under fine grade abrasives starting from 220 Grit and finer. Their flexibility helps your abrasives sand or polish the contours of rounded and domed workpieces and gives them a shock-absorption effect as well.

Simply stick them onto the Backpad before applying an Abrasive. They come in 3 flexibility options: Bumpon, Medium-Flex and Soft-Flex.

- The 3M Bumpon (Black color) cushions are great for working on lapidary with Diamond Abrasives or sharpening rounded edges on tools with Trizact abrasives.

- Use the Medium-Flex (White color) when working on domed/rounded Polymer Clay, Ice Resin, Amber, and other soft materials. We recommend these abrasives Microfinishing Film, Polishing Film and WetOrDry Polishing Abrasives.

- Use the Soft-Flex cushions (White color) when working on very soft and very rounded pieces made with Polymer Clay, Ice Resin, Amber, or other soft materials. We also recommend these abrasives: Microfinishing Film, Polishing Film and WetOrDry Polishing Abrasives.
