Mirka Autonet 2-3/4-in. x 33-ft. P320 Mesh Grip Sanding Roll for Dust-Free Sanding (AE-570-320)

Mirka AE-570-320 Autonet Mesh Grip Roll is a P320 abrasive roll built for extra-fine sanding and surface prep. This is a sanding roll designed for automotive refinishing and dust-controlled finishing work. Model Number: AE-570-320. With a 2-3/4 inch width and 33 to 33.5 foot roll length listed across source data, it gives you a long supply of cut-to-length abrasive for sanding blocks, mouse sanders, orbital sanders with roll attachment, and vacuum-assisted setups.

What matters here is the mesh construction. Unlike standard paper sanding sheets that load up fast, the Autonet design is built to reduce clogging and pilling while moving dust through the entire abrasive surface. In real use, that means the abrasive stays cleaner, keeps cutting more evenly, and does a better job on painted panels, fillers, and other finishing surfaces where packed dust can ruin consistency.

The P320 grit makes this roll a practical choice when you are no longer trying to remove material aggressively and instead need control. It is an extra-fine grit suited to smoothing, blending, and refining a surface before primer, paint, or final finishing steps. The aluminum oxide abrasive gives it a familiar, dependable cut, while the closed-coat layout is tuned for consistent coverage across the work area.

Mirka also built this roll for shop efficiency. The perforated format lets you tear off the size you need instead of trimming every piece with scissors or a knife. That is a small detail, but it matters when you are moving from panel to panel or switching between hand sanding and machine sanding. Less setup time means more time sanding and less wasted abrasive.

For dust control, this product really makes sense when used with a vacuum system. The whole point of the mesh is that dust extraction is not limited to a fixed hole pattern, so you get more flexibility across different pads and hand sanding setups. If your goal is a cleaner workspace and a more consistent finish, that feature matters as much as the grit itself.

This Mirka sanding roll is best suited to automotive refinishing pros, collision repair shops, painters, and serious DIY users who care about surface quality and dust management. If you want a cut-to-length abrasive roll that works clean, resists loading, and fits into a vacuum-assisted sanding workflow, this is the right type of abrasive to keep on the bench.
