Brunswick's website states that they sand it to 400 grit, then polish it with rough buff. The shop that I deal with showed me the rough buff and it looks like a rubbing compound. When I have used rubbing compound on a ball, it made the surface more smooth, but did not do much polish wise. Maybe the equivalent of around 1000 grit in regards to the smoothness.
I would play with it a little bit-what can it hurt? You can always adjust if necessary
