I used the most coarse grit I had, 60, because removing the ano takes a bloody eternity. Once you've got that off the I just polished it up as normal, think I went 150→240→1000→1500→Mother's Mag.
Really half arsed it because it won't be going on a fancy bike or anything, so no one's going to get a close look at it. You can see for example that I didn't bother to do the tabs for the crank bolts as it was an awkward area and I couldn't be bothered. But if you look up Jeff Jones XTR cranks people get them to a mirror finish - probably just a couple more hours of work (same process, just a different crankset).
Preserving it I don't know! I was googling the Jeff Jones XTR cranks for ages trying to find some example of them after being in use for a year but nothing came up. Decided I didn't really care that much and could always polish them again (the Mother's Mag and fine grit sandpaper only takes a few mins). I think you can top coat them but I don't have any around so not going to bother.
Translated it, some good info actually. He did it with sandpaper but polished with those discs in some machine or other. Guy lower down in the thread says wiping WD40 on works to preserve them??? Weird

Also did a seatpost and might do a stem as well.
Edit: this guy did a great job with power tools, I can't read Spanish though. Here's some very shiny Shimano road cranks
