I would try any polish that will not change the surface prep first meaning no grit, what you have will work,brunswick factory finish,or storms extra shine. These polishes will only shine the ball add slight length and improve back end hook all on dryer conditions.If you want go to the ROTO Grip web site and check out thier ball maintenance suggestions. look at the serial # on the ball there were 2 pours they start with 04- more even reacting,05- slightly more aggersive midlane and back end. Mine is the 04 and with polish, storms extra shine it's a monster on all medium conditions.
