This topic has been covered a bazallion times.... its a polish application that will be destributed by bwick later this month or early next month.
It does not effect the grit finish of the ball, some one called it a "grit filler". So if you wanna do surface changed, do so with a schotchbirte or abrasive of choice, and THEN add the rough bough finish.
