I guess I'll weigh in to this fray a bit with some of the safety(Gloom and Doom:eek: ) aspects.
First - Jack - I have to take you to task about using box fans (which I also had always used before) THESE FANS ARE DANGEROUS AND NOT EXPLOSION PROOF!!! It sometimes scares me that I haven't blown myself up yet. I bought a greenhouse/ barn fan fairly inexpensively from these folks:

The 12", $119 version plus ~$20 for shipping - and it really moves air, 1050CFM. You don't need but about half of that for a single stall garage. Consider their variable speed adjuster for another $50.
Secondly, most of the new BC/CC paints are either an isocyanate or benzol blend of nasties that can scramble your brain from a very short time to permanently. It can effect your respiratory system the same way as well. For sure all of the clear coats have Isocyanates. This means an a minimum, a charcoal canister mask, eye protection, nitrile gloves, head sock and a bunny suit. Better is a supplied air system - which I bought as I have had some respiratory reactions to these paints. Acryllics aren't quite as bad but the solvents can render you 'speechless and breathless' for a day or so if you don't use precautions like a charcoal canister mask.
As far as the paint brand, stick with what you can buy locally is the best - DuPont is my favorite, but others have good luck with PPG, NAPA's Martin Senour, RM(BASF) Kirkers and House of Kolor. I also really like Southern Polyurethanes epoxy and 2K along with their Universal high solid clear.
Equipment is another complete thread or several - big enough compressor, HVLP guns, DA sanders, sanding blocks, brands of sand paper, etc, etc, etc.
Whatever it takes it ends up cheaper then paying someone $10-$30K for a custom paint job that might be better then yours, but then might not. It is extremely time consuming just for the prep time to make the surface good enough for paint - 100 hours is not an unreasonable number for an OK car with minimal defects, more if you have dings dents and rust that have to be "cured"
