I once had a Valiant with a white engine bay and if someone 2 towns over got grease on their hands it seemed to wind up showing on my white engine bay! the Chili-pepper red was actually my second choice. I was leaning toward black but when I started looking around, everyone has a black engine bay. So, red it was, to match the interior.
I know what ya mean about the grease on the engine bay, I had a white 66 Barracuda that had the same troubles, the paint was nowhere near the quality of yours, but it was still hard to clean
