OK, so here's what I ended up with. This color is Vermillion obtained from the Space Age auto paint store on Country Club in Mesa AZ. The folks at Eastwood were able to give me a trade name (One Shot) for a line of pre-mixed enamels that I could find locally in the Phoenix area. It was $14 for a 1/2 pint. I thinned it with a high temp rated thinner and sprayed on a few coats.
Previously, before posting my question, I had sprayed on the hi-temp Chrysler Red from a rattle can, but it was too red relative to my engine. The Vermillion is less red and more orange than the Chrysler Red. And -- to my eye -- is more pleasing.
Thanks for the leads on the paint colors.
