Rough Buff is a very aggressive, abrasive rubbing compound that smooths out the surface of the ball. If the starting surface is fine enough, around P1500 grit, and you're using a spinner, you could get a shine from it. By hand, it will just smooth out the surface.
These days, Brunswick starts with a P500 grit surface. And then uses either Rough Buff by itsekf or RB plus polish. I've seen one ball where they used Rough Buff over P500 + P1500 grit.
5 - 10 years back, Brunswick used to apply Rough Buff over a 220 grit (US/CAMI grade sandpaper). That was used on balls like the Absolute Inferno and MoRich's Shock and Awe balls. Back then the result was roughly equivalent to a P4000 grit surface (Specified by Brunswick tech support back then).
You can use Rough Buff to smooth out many grit levels using hand or spinner. The main problem, like Storm's Step finishing compounds, is that the final surface is determined by where you start (grit level) and how much compound you use, how hard you press and how long you do it. With all those variables, the results can also be quite variable. you have to keep track of he appearance and the factors you change each time you do it. The abrasives in the compound bread down into finer and finer abrasives, just like all sanding pads do: Abralon, Siaair, Mirlon, Scotch-Brite and Neat.
