Paint help

I completely suck at painting, doesn't matter what type. However, I used rattle cans on my '72 Fury's 360 and it came out "ok". I used high temp silver on the stock exhaust manifolds after cleaning them really well. The can said install engine parts and bring up to operating temp for something like 20-30 minutes. That wasn't possible at the time. So, I turned the oven on to "clean" (highest heat it would go) and put them in there to cure. Did my (ex) wife approve? I don't know, she was out of town with the boys at a soccer tournament and I wasn't about to tell her I was cooking car parts while she was gone, lol. The paint held up pretty well for about 5 years, but when I pull the engine again, they'll get re-done. This time if I can't get them ceramic coated, I'll use the grill like @pishta said above.
