Hey alex,
Haven't changed the original cover of my Artillery yet so this is a little bit of a guess. From what I see and it stating that it is a compound finish/polish, (using a spinner) I'd try a grey pad with Clean and Tacky on it or you can apply Cleen and Sheen over a 600 finish. In the past, any of our "compound" finishes have been reproduced with Cleen and Sheen. It's just a matter of how much grit you want to use underneath it to help determine how much grab you want from the ball. Hope this helps some...
