Don't be afraid of rattle cans. You can get just as good results with them as you can with a spray gun. Both engine and engine bay were done this way. Rust-O-Leum lasts forever, too.
If Rust-O-Leum is good, and if I can get it in the right color (or at least close), I have absolutely no objections to that, and would prefer it to make things easier.
