Ok i have storm xtra shine polish and it says that it take the ball to 3500 grit and i also have some 3m finesse-it 2 what grit does it take the ball to. annd if i sand the ball down to 1200 grit and then polish it with the storm polish will the grit increase and if i do the same thing sand ball to 1200 grit and polish whith finesse-it 2 will the grit change.  I am new to this so sorry for the stupid questions.
