[strictlypersonl]

Contemporary "fresh" paint is already pretty stable, unlike back in the olden-days when it took a long time for paint to cure (and the solvents to evaporate). Paint is now cured by a chemical reaction that is pretty much done within a couple of days.

You can't sand or buff uncured urethane-based paint.

Our local painters bring the cars here on a flatbed or open (albeit shielded) trailer and I have yet to see any damage from the trip. I would be more cautious with a thousand-mile trip, but a short one should be OK.
