The Mirka Autonet 2.75" x 33.5' Perf-Roll Grip, model AE-570-080, is a net abrasive perf-roll built for sanding and surface preparation in automotive refinishing. This is a perforated net abrasive roll designed for fast stock removal, cleaner sanding, and better dust extraction. If you want an abrasive that keeps cutting instead of loading up early, this is the kind of product that makes a real difference.

What sets Autonet apart is the open net construction. Instead of trapping dust on the face like traditional paper can, the mesh-style design allows dust to move through the abrasive more effectively. On the job, that means less clogging, more consistent scratch pattern performance, and less time stopping to swap out worn or loaded strips. Mirka specifically developed this line for automotive refinishing, where surface quality and repeatability matter.

The P80 grit on this version is a practical choice when you need a stronger cut for prep work. It is suited for more aggressive sanding steps before moving into finer grits. Because this is part of the Autonet range, you still get the benefit of reduced edge wear in finer grit versions across the line, but this P80 option is the one you reach for when material removal and speed matter first.

The 2.75 inch width and 33.5 foot roll length make this format useful for shops that want flexibility instead of being locked into one pad size. A perf-roll format lets you tear off what you need for the task at hand, which helps reduce waste and keeps consumables easier to manage at the bench or in the cart. The grip backing also makes it a practical match for hook-and-loop style sanding setups that use strip abrasives.

Mirka also calls out excellent initial aggressivity and long life, and that combination matters. A lot of abrasives cut well for a short time, then slow down once dust starts packing into the surface. Autonet is built to avoid that problem. For body shops, paint prep, filler shaping, and general refinishing work, a longer-lasting abrasive means more usable sanding time per strip and more predictable results from start to finish.

This product makes the most sense for automotive refinish techs, collision repair shops, and anyone doing repetitive sanding where dust control and abrasive life directly affect workflow. Serious DIY users working on vehicle restoration can benefit too, especially if they already understand grit progression and want a cleaner-running sanding abrasive instead of standard paper rolls.
