One of the Brunswick reps had indicated in the past that Rough Buff on top of their "standard" 220 grit US sanding was first equivalent to 2000 grit Abralon (Abralon is FEPA standard. In US/CAMI standard, that's 1000 grit). Later they changed it to 4000 grit Abalon (2000 grit US/CAMI).
Remember Rough Buff is an abrasive compound. WHat you wind up with depends on 2 main factors:
1. the sanding level on the ball you start with. RB directions say if 220 grit is too rough, then go up the line, 320 grit, 400 grit, 600 grit, etc, and adding Rough Buff until you get the reaction you need/want.
2. Since it is an abrasive compound whose abrasive continually breaks down into smaller and smaller pieces, the final finish depends on
a. how much compound you use, AND
b. how hard you press, AND
c. How long you spend on the spinner, doing both of the above.
It is very variable, with lots of dependencies. It is not fixed, it is not a black and white, on and off type of situation. FYI This is true for every polish that has an actual grit number on the bottle. They are usually maximum numbers, not an "every time" number.
