Engine Bay

If it was me, I wouldn't touch it. That looks better than the majority of the engine bays out there. If you're going to wind up doing it the right way at some point down the line, I'd say it'll probably look more unnatural if you do a rattle can job right now. At least the way you have it, it matches the rest of the car.

I did my engine bay the right way a few months back and it was one of the least fun things I've done on a car. I wouldn't want to do that any more than I need to.
