I uses 40/60 but mainly because that worked better w/the low-end asperator-type set-up I was using at the time. 20/40 is recommended for what you're doing, but I would mask/plug off decks, guides, seats, and any other machined surfaces unless the surfaces were being renewed.

I'm sure you're aware of this, but use a respirator and hood along w/gloves and protective clothing to keep the silica out of and off of you.
