I did a fair bit of powder coating a few years back.
The Eastwood kit and an old electric oven work great for smaller stuff. A clean dry air supply is a must, as well as a breeze free booth. Custom colours can be ordered from several spots. We have black white and silver in 50lb boxes. I've done some other colours as well, but only in the one or two pieces at a time.Only needs a minimal 3 psi air supply, parts need to reach 400F for 20 minutes or so, IIRC, to cure properly, parts must be squeaky clean and free of fingerprints.
We used a standard kitchen oven for all our small parts. Any thing that can be hung can be cured.
We also have a 6000 watt 480V Infrared heater as well, but being directional, it takes constant attention and rotation during cure to get a good coat.
A lot of local shops use the process now days. Our Fab shop has an oven big enough for a car, or a 20' skid shack. you may want to source out your larger parts to a pro if you want bigger stuff done.
When properly done, it's a very nice durable coating, and custom effects can be done if you know how.
