Three-hundred-twenty-grit sanding discs were part of my surface-finishing purchases.
The featured Amazon option is Dura-Gold Three-Hundred-Twenty-Grit 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
Dura-Gold provides five-inch hook-and-loop discs. The 3M and Dura-Gold sheet alternatives use the same grit number in a hand-sanding format.
3M Wetordry 320-Grit Sandpaper
These fine-grit abrasive sheets have a waterproof paper backing. The sheet format can be cut or folded for hand sanding and sanding blocks.
