Rough is a light stone finish, not a sanding cone or 400 grit paper. I bring it in with a cone and just take the sheen off with a stone. Sometimes go back over it lightly with a cone again to knock off any peaks if it feels too rough.

That's what the pros always wanted when I was porting daily. They would put them on the flow bench to be sure they were good before wasting time/money on a match race.
