The paint technology of today seems to require an orbital finishing step to pass the test of time. For that matter, an immediate wash between buffing steps, or a simple spray of alcohol-based glass cleaner helps to expose the ultra-fine rotary swirl that is almost certainly present.
I say helps because sometimes there are instances when the paint allows solvents to penetrate or permeate the surface. When this happens, the paint looks fantastic until the solvent 'gasses out', or 'evaporates'. Then you'll see the imperfections left by the rotary. For me, it's best to just follow up with the orbital while you've got everything out and you're planning on doing it anyway.
Regardless of whether it's a one-day detail, or a thirty hour paint polishing session, I will do a final pass by hand or orbital. Since I'm the only guy that I can go to if I have a problem, I'd rather avoid it and do the extra step.
