From the Ebonite website it says that the One is sanded with 4000 grit Abralon then polished with PowerHouse Factory Finish Ball Polish. If you are bringing it back after use you will want to start at at least 1000 grit abralon and work your way up to the 4000 grit abralon. You can use what ever polish you are comfortable with and bring it back up to factory finish or use PowerHouse Factory Finish if you have some available. Hope this helps.
