I have a 2002 Trek 5200. It was in pretty bad shape when I got it. All the decals were torn and there were several minor nicks in the carbon frame but noth8ing severe enough to warrant any kind of repair. I can't remember exactly but I started out with something like 600 or 800 griit and then went 800 > 1000 > 1500 > 2000 then rubbing compound, polish and wax. I was very happy with the results. Don't' quote me on the exact grits that I used but I remember using somewhat of a sequence like above.
