Engine Paint Questions...

In the near future I will be repainting the enging and engine compartment on my 1500. I'm not sure what color to paint it. I thought about just painting it black. Does anybody have a link to a good step-by-step article for painting to engine compartment/engine?

Also, I don't have an HVLP set up. Would painting with an Aerasol Spary can be a No No? I would rather not pull the engine and risk creating problems just to paint the engine.
