There are grit charts available on-line but 500 siaair and 500 grit sandpaper are different grits. Abralon and siaair use the same grit rating system.
I believe that chart is in our FAQ section.
I think the 5500 grit reading is coming from the Rough Buff, not the sanding pad.

I'm sure you're correct Mike. My point wasn't how much the polish potentially smoothed out the ball but rather the way it appeared that the questioner thought 500 abralon and 500 sandpaper were the same thing.
