Although Autonet Discs are similar in design to Abranet® Discs (the original net mesh disc), they have been optimized specifically for use on automobile surfaces.  Primer, paint, and plastics (such as headlight lenses) can all be efficiently sanded using Autonet discs.

Interestingly... Autonet discs last longer and cost less than Abranet discs. 

Autonet's net mesh technology will surprise you, just as they did a friend of mine.  He restores a lot of plastic headlights.  His initial impression was very interesting, but not surprising.  "Compared to my other discs, these are so easy to control, and they cut fast.  I thought I was doing something wrong before.  What a relief!"

He was using Abranet Soft discs, and was referring to the fact that when used wet, ordinary film-backed discs have a tendency to hydroplane.  When this occurs, the disc wanders about, and can be difficult to control.  Autonet's net mesh design eliminates this problem by allowing the lubricating liquids to easily migrate to and from the work surface, using the holes in the mesh as a passageway.  By the way- my friend now uses Autonet discs for his heavier work, and finishes using Abralon discs. 

Working with wood, body fillers, or fiberglass?  Then you’ll appreciate how well a vacuum system works with these discs.  In fact, net mesh technology is immensely popular in the woodworking and drywall industries.  Both of these industries are notorious for being dusty, but not anymore... thanks to the net mesh technolgy used to make Autonet!

Leveling ability versus Contourability.
Throughout this site, there is a lot of discussion pertaining to the leveing ability and contourability of a disc.  For the record:

Leveling ability is the potential ability of a disc to plane a surface flat (or true).
Contourability is the potential ability of a disc to conform to curved or complex shapes.

In terms of leveling power and contourability, Autonet discs deliver the best of BOTH worlds.  By choosing the ideal interface pad and varying machine speed, Autonet discs become very versatile!   Autonet discs are a bit less flexible than Abranet discs, primarily due to its thicker net mesh material.  Compared to film-backed discs featuring a similar grit size and backing thickness, here is how Autonet discs rank:

Autonet discs work well wet or dry, and stay clean longer than traditional film-backed discs.
If most of your sanding work is geared towards automotive primers, heavy orange-peel removal, or plastic headlight lens restoration, Autonet discs will save you time and money. They are available in 3" and 6" diameters, in 80-800 grit (specific grades are listed here). If finer grade discs are needed, consider using Abralon® or Abranet® Soft  discs.
