You should start with like a 1500 grit paper and work your way up to 3500 or 4000 grit.
When you are finished you will have to buff it out to bring the shine back. I use Meguiars, start with a heavy cut cleaner, finish with #9 swirl remover and top it off with a coat of there cleaner wax

Yes, sand first to remove imperfections finishing with a 4000 grit paper.
The buffing wheel and rubbing compound will remove the scrates made by the paper

Have you considered just sanding and a couple more coats of color? I myself dislike the look of cut and buffed paint compared to a well prepared and applied finish, plus most times its waaay less work to reshoot . Be aware thet if you have dirt or runs or other surface defects, they will eventually re- appear as a ghost after color/ clear sanding and buffing. Which omni system are you using ? And what are you working on ? car, truck, tractor?
More information will get a more accurate repair strategy. And better results

Sounds like we're painting a Corvette, not a tractor. A tractor never had a paint job like your talking about. In fact, I don't think any of my cars did either. Spray it and let it dry, DONE. Bob

With the proper compounds and buffing pads, finish sanding at 2000 is plenty fine enough. You need to be sure you have adequate paint coverage to start with, atleast 3 medium coats, imo. If you have no experience, extra care must be used around bodylines, crevices, etc....very easy to sand/buff through the high spots.
