Reddit mentions of Speedokote High Gloss Jet Black 2K Acrylic Urethane, 3:1 Gallon Kit w/Activator, SMR-9705-M

Thank you! It seriously looks way better in pictures than person. I made legions of mistakes while doing it. Here's a better pic of the car with the two-tone black and blue: http://imgur.com/tBzpxnj

A couple of things I learned though:

Definitely get a big compressor. The compressor I used had a relatively small tank and was weak. If the compressor is running a lot it can create moisture in the air. Additionally, you don't want to spray while it's running because it'll create pulses in the spray pattern. I painted the black hood and stripes once I had the car back in Texas with a proper compressor and it went way smoother.

Spray more layers than you think you need. I thought I could get away with 3 to 4 layers of color. I should have gone with 6 to 8. The pros will say that's too much, but the pros don't wetsand half of it away to fix imperfections. More paint means you have more real estate to work with after the spray to sand it back and make it mirror smooth.

I would definitely spray a clear coat. The Bellett was parked outside in the elements in Japan for about 2 years before bringing it to the States, and while that didn't ruin the paint job, the constant washing with random towels that I do to keep it somewhat clean put lots of tiny scratches in the paint. Normally, I could buff these out, but a lack of clear combined with not enough layers of color sprayed means I can't do any buffing for fear it'll burn through the color and the primer will start showing.

Also, go with solid colors. I sprayed a solid blue/black on the Bellett and it's so much easier than trying to get some fancy mica or metallic to work. Because I'm a cheapskate, I used Speedokote Jet Black (https://www.amazon.com/High-Gloss-Black-Acrylic-Urethane/dp/B00TXDP85W/ref=sr_1_1?ie=UTF8&qid=1492625678&sr=8-1&keywords=speedokote+jet+black) for the gloss black bits (hood, stripes, cowl). It's super easy to work with, sprays evenly, and has a nice strong finish. Plus, it's cheap! You can see on Amazon it's like $80 for a gallon kit, which is enough paint to paint a whole car. So, if you just want a jet black car (with no clear), you could get some high build primer and the Speedokote Jet Black and still be under $200 in materials.

Ventilation is important, but more so for your health than the paint job. If you're doing a garage job, there's nothing you can do to keep gunk, dust and stuff out of the paint. That's another reason why I suggest spraying lots of coats. You can wetsand some of the stuff back to a smooth, clean finish. The ventilation helps pull the paint floating in the air out, which keeps it from getting so smokey in the room that you can't see. However, when I did the hood and stripes on the Bellett, I had no ventilation at all and if anything, the paint worked out better than the blue did (which I hung up plastic sheets and had a ton of fans to try to emulate a proper booth as best as I could).

Hope that helps and good luck with the quarter panels!
