Heck, I'll let one set 4 or 5 years before doing anything to it after paint - but that's probably just because I'm slow!

Factory paint is good to go right off the lot.
There's isn't really a hard and fast rule for respray paint because there are too many different paint formulations and too many variables that affect cure time. Check for your coating manufacturer's recommendations (don't trust the painter's opinion!). I've heard 90 days is recommended by most manufacturers.

The answer to this question depends a lot on what you've painted with and what you are asking about doing. The real answer is that you need to check with the paint manufacturer and/or read their spec sheets.
If you are spraying a base-coat/clear-coat system or two component urethane with hardener, it's not at all unusual to wet sand and buff 24 hours after the top coat is applied. As mentioned, wax and other coatings applied over that are generally postponed (and aren't necessary) for months. If you were applying lacquer, the wet sanding and buffing may start on the same day because the solvent flashes and evaporates so quickly. As with urethanes, waxing would be put off for quite a while. From memory, acrylic enamels require the longest delay before you work on them.

Jack:
That is my concern as well, because when assembling her you will most likely get a couple of chips. If waiting for the coats to be fully cured will minimize them then that is another story.
I will stop by my friends bodyshop today or tomorrow and get a opinion from them. He does bake em, but I will ask about unbaked. You can use this information for a comparative.

I stopped by today and the "previous" owner my friend said to wait at least 1 week, so I would wait two to play it safe. Let me know what your painter tells you, because I am curious.
The previous owner/a friend of mine sold his shop. The new owner has no idea what an AH is. This is no big surprise. The good news is that his wife works with me, small world.
I guess that I will throw him a small job and see how it goes. It is very hard to find a good shop here.

As a finish cures it outgasses and hardens progressively, quicker at first but approaching its final hardness over an extended period. As an example Dupont says that you can handle/assemble panels coated with their ChromaSystem 1780S clearcoat after 6 hours-overnight (air dried) but you shouldn't use wax for 120 days (air dried or baked).
Wait time to minimize chips, scratches and dings isn't something you can pin down precisely because incidents that chip, scratch and ding aren't precise, repeatable or predictable.
Whatever time you choose to wait it's always prudent to do whatever you can to avoid damage. If you want to cover some area while you're working close to it don't use just any old rag or drop cloth, they're abrasive. Try to use a clean towel that's soft enough to use for polishing, like microfiber or 100% cotton terry. If you mask off any areas use only low tack painter's tape and don't leave it on the panel longer than recommended. If you do use tape remove it by carefully peeling it back on itself, don't just pull it straight up.
To remove light dust, fingerprints and smudges you can use a fresh paint safe detailing spray like Meguiar's #34 Final Inspection and a microfiber towel (wipe gently, don't rub). For heavier accumulations of dirt it's best to use a fresh paint safe soap like Meguiar's #00 Hi-Tech Wash.
