CHANGE IN OPINION!!
Just saw Parker Bohn's Anacondas drilled for the Great Adventure series.
This ball looks NOT like P3-4000 grit matte finish, as previous 220 grit + Rough Buff finished balls have looked in the past. This ball definitely almost has a light shine to it, like someone took a very used P4000 grit pad to a P4000 grit finished ball. It has that light shine that normally says the pad was too used.
So I'd guess that 500 grit SiaAir pad is closer to 360 - 400 grit US (than the 220 grit US the Absolute Inferno used to have) and the application of RB on top of that makes it smoother still than P4000 grit because RB is such a rough abrasive. You might want to take a P4000 SiaAir or Abralon pad to this ball. In stock form it may not handle the oil you think it should. Try and decide!!
