Mirka Autonet 2-3/4-in. x 33.5-ft. P120 Mesh Sanding Roll for Dust-Free Sanding (AE-570-120)

The Mirka AE-570-120 Autonet Mesh Grip Roll is a perforated abrasive roll made for dust-reduced sanding and surface prep. This is a mesh abrasive roll designed for fine sanding, surface preparation, and automotive refinishing work. Model Number: AE-570-120. If you need a roll you can tear to size for consistent hand sanding without loading up as fast as traditional paper, this is the kind of abrasive that earns its spot on the bench.

What matters here is the Autonet mesh construction. Instead of trapping dust on the face of the abrasive, the net structure allows dust extraction across the sanding surface. In real use, that means less clogging, less pilling, and a more even scratch pattern over the life of the strip. For anyone sanding primers, fillers, paint, or other refinishing surfaces, that usually means fewer interruptions to knock dust out of the abrasive and fewer wasted pieces.

The P120 grit sits in a useful middle ground for finish prep. It is fine enough for controlled surface work, but still aggressive enough to move material when you are leveling or refining before the next coating step. Mirka pairs that grit with aluminum oxide abrasive, which is a proven choice for general sanding because it balances cut speed, durability, and predictable wear.

This roll format also makes the product practical. The width is 2.75 inches and the roll length is about 33.5 feet, giving you a long supply that can be torn off as needed. The perforations matter because they save time when you are moving through repeated sanding steps. Instead of stopping to measure and cut each strip, you can tear clean sections and keep working.

The backing is listed as polyamide fabric, with supplementary data also referencing film and paper. What is clear from the source data is that this is not just a standard paper sanding roll. It is part of Mirka’s Autonet line, which is built around a mesh abrasive structure for cleaner sanding performance and reduced edge wear in refinishing applications.

The Mirka AE-570-120 Autonet Mesh Grip Roll makes the most sense for body shops, paint prep, automotive refinishing, and anyone doing repetitive hand sanding where dust control and abrasive life matter. Serious DIY users can benefit from it too, especially if they are doing detailed prep work and want cleaner sanding than a basic sheet roll typically delivers.
