Have any of you painted your shroud...

[slam59]

or any other plastic area or part under the hood? If so, did you use high heat engine paint or plastic paint? My mechanic friend said to use the high heat engine paint. I thought about black dupli color paint thats meant for plastic. Is it ok to use the engine paint on hard plastic like the shroud? I am taking off the metal part on top of the shroud to paint it black. The shroud cleaned up good, but there are parts that are darker and shinier than other areas so I thought about painting it. Are there plastic cleaners or things that might renew it back to black? Here is the shroud below. In excellent shape, solid, with no tears or rips or pieces missing. Original GM part that came off a 74 like mine.
