repainting the engine bay requires dropping the engine and painting it with one layer of base coat. definitely not worth it. if you look at your engine bay, it is not the same color as the rest of your car. a black car has an engine bay that looks more like a gunmetal color. my midnight blue color lacks a few coats and a clear. minus the strut towers and the interior of the engine bay, the whole car is orange, down to the door jams and underneath all the plastic moldings in these areas.
