Either Granat or Brilliant would be the way to go then.
"Granat is our most long-lasting and highest performing abrasive and is well suited for nearly all applications, including bare wood, paints, most modern paint systems, VOC clear coats, plastic materials, solid surface materials, acrylics, and composites. Hardened Aluminum Oxide, Synthetic Resin, Closed Coated.
Brilliant is perfect for paint, fillers, primers and finishes like lacquers and varnishes; its antistatic coating is compatible with water-based products. Aluminum Oxide, Synthetic Resin, Closed Coated."
I personally only have Granat. We do mostly interior remodeling, a small amount of cabinet building, and just a general variety of tasks. Haven't tried anything else yet but since we travel about all the time and do a variety of finish's or bare wood sanding, I went with Granat. Been very very pleased so far.
