After the crowning, I pretty much just start playing. The frets don't shine, and bends feel a little gritty (but sound fine), for a few hours, but just playing the guitar will burnish the frets. You won't be taking enough off to make any difference, BTW, if you are just burnishing the frets with some sandpaper. I'm just too lazy to do it.
Crowning is what freaks me out. You see all this metal grinding off of your frets, that you just leveled. I still tend to leave them a little flatter than they should be, I think, for worry of taking off too much.
I just did my 7th neck yesterday, Ron Kirn style. I'm also in Ohio. :)
