The lustre king's normally have a car fax type of polish, can't think of what it is really called, the polish will get into the pours of the ball and not allow the ball to react as designed, kill the ball to a point. To get the ball back to what it was will require a resurface after the lustre king, so be careful going this route. Best bet is to get there early, find someone with polish and get to work on it.
