I believe the ball is supposed to be about 800 grit US (edited).
First I would sand it to 4000 Abralon (P4000 = 2000 US). Then try it to see what you get.
Next I would sand it to approx 600 or 800 grit US with a green or a light grey Scotch-Brite nylon pad. Then I'd add some polish, medium gloss, with a non-abrasive polish like Valentino's Snake Oil or other non-abrasive (just so you know the underlying grit level).
Next, I'd go up in sanding level to approx 1200 - 1500 grit US and add a non-abrasive polish again.
Next, I'd complain to the manufacturer. Tell him how it was drilled and which surfaces you tried.
