It's anyone painted the valve cover? Or any other parts in the engine bay? WhatHeat paint did you use? How did you do it?

 

Many have painted many things in he engine bay. Not sure what kind of paint they used. Sorry to not be of much help. There has to be an engine block paint that you can pick up in a rattle can at the auto parts store or paint store that would do the job. Though it probably wouldn't match the body paint very well.
