If you paint anything under the hood, I suggest using some kind of hi-temp paint. That basically leaves you with (although there are a few other choices) Duplicolor Engine Enamel (available in several colors) or Duplicolor MetalCast (Takes a long time to dry, like 4-5 days for full drying). Always prep the surface with sanding first, and at least two or three THIN coats of primer for adhesion purposes.
