I bought mesh sanding discs during the sequence of preparation and finishing work.
The featured Amazon option is 3M Xtract 120-Plus Net Discs.
Where it fits my build
I taped the boundaries and covered the areas that would not be painted with plastic sheeting. I then sanded the exposed areas with an orbital sander and 60-grit abrasive, blew away the dust with a compressor, and cleaned and degreased the surfaces.
I mixed clear bedliner with white tint and sprayed the van. After it dried, I removed the masking. The tape and sheeting stage alone took around eight hours, and the finished edges still needed some touch-up.

My build notes
The most useful detail in my diary is the result, including the problems. Rust-Oleum pooled and dripped in places, and trying to repair one area with a paintbrush made it worse. I wrote that I would use a foam roller for touch-ups and preferred the more consistent finish I had obtained with RAPTOR.
Masking, preparation and application method each became a substantial part of the exterior-coating job.
Alternative products
Two alternatives to compare
The featured 3M net discs use a 120-plus grade, while Mirka's mesh option is 400 grit. Diablo's 120-grit discs provide a conventional disc format alongside those two mesh choices.
Mirka Abranet 400-Grit Mesh Discs
These five-inch mesh discs provide a 400-grit abrasive surface. Their hook-and-loop backing attaches to a corresponding sanding pad.
