If it's for outside use, there's other choices than Rustoleum. My last go-around with that brand has put me off it indefinitely. Stuff would lift off with naptha after two weeks drying time in the summer heat. Naptha normally doesn't affect most dry and cured finishes. You could try the oven for drying, if the parts are small enough or use heat lamps to see if you can get a better cure.
Last time I needed a flat black finish, I went with urethane in a spray can. That brand disappeared overnight off the paint store shelves when CA went with their revised VOC regs. The stuff I've sprayed with it has stood up well, though, still have some full cans of it. There's some flat epoxy sprays that work pretty good, not as durable as the urethane, though.
You have a much wider paint selection if you can get even a small spray gun setup, auto finishes are extremely durable and you can get just about any color you want. Downside is cost for the paint, though. Small touchup guns like I started with run $15-20 on sale at HF, work great for the odd small paint job and usually don't need a huge compressor.
