Oh man. I've seen it. It does look great. I did say I have nothing against powder coating, and I do use that process extensively.
I didn't want to color-match my valve cover to my paint because a white car with a white engine bay and a white block and intake manifold would have looked really boring with a plain white valve cover. It looks great on cars with more colorful paint jobs (like yours), but in my case, I sort of HAD to polish it because of what had done to everything else. Nothing else would have looked right on the center piece of the engine bay. White is a difficult color to compete with.
It's really messed up that I'm so picky about that because when my car's hood is closed, the rest of my civic looks like a POS bucket.
