It's pretty easy. You can't use your household stove (poisonous fumes), but you can buy a used junker. I bought a little toaster oven at a garage sale that works great for all those little parts. It's a pain to set up and prep everything, but not having to wait for paint to dry is a welcome plus.
Most powders cure between 300-400 deg so you should be fine. I have only had mine a years or so, so I have really only tried 4-5 powders, but yeah you get what you pay for and once it’s on you're pretty much stuck with it so don’t skimp. FYI you would be amazed at exactly how little room there is in a “full size” kitchen oven. I just did my rack I made for my Moped and it barely fit, so did the rear fender on my bike (and it’s bobbed!). I had to make special holders in both cases just so they would fit in cock-eyed. So if you are planning anything large, think ahead!
I am wanting to paint all the chrome parts on my truck black. But my front bumper isn't going to fit into anything I could possibly own.
