At what grit do you find this effect begins diminishing ?

If I am hogging away material, I start with a 36 grit belt, then 80, 120, 240, 400, then I progress through Gators down to A30. The biggest area of change is after 400, where I switch to Gators then Trizact belts. If desired, they go to 2500 grit. I usually stop at 1200, then switch to cork belts with different abrasives, or buffing compounds. Essentially. once your "reflection" starts to clear up, say at a hazy finish, I don't see rapid rusting from grinding heat/water cycles.
