I recently contacted Galen(Legends/LaneMasters layout and coverstock "guru") about getting my Big Kahuna and KONG back to their OOB condition; here are the EXACT steps that he conveyed to me:
1) 400 wet sand
2) 800 wet sand
3) light coat polish with THEIR polish(provided with the ball's purchase)
*** Contact them(888 526-3645) to purchase OR to know a suitable substitute ***
4) 800 wet sand (4 directions)
5) NEW grey scotchbrite
*** Then, to FINE TUNE the ball's reaction even further, you can hit it with light coat of polish OR 600 wet sand(depending upon the type of adjustment that you desire; of course, a strategically placed weight hole is another option in this regard.
I speak the TRUTH !!! This is the latest and the greatest info to answer this particular question. I hope that it helps !!!
