Yes... I dislike Raven's choice of colors, across-the-board. It's his choice. I just don't use them that often because of it.
As for the B17... I did some checking, back when I made it, and metal B17s are highly reflective. Hell I even built a 48th scale model of one, and used real aluminum foil for the surface, the damn thing is a freaking MIRROR (and this isn't a polished surface, it's scratched and mangled to get it on the plane). To me, I see it as fairly accurate, based on photos and the real metal used on the model I built. I think that maybe, if anything, the materials file aggravates this situation. I spent a lot of time on it, and was never 100% happy with it, but found something I was "mostly happy" with.
I can supply the bitmap of the skin if folks want to play around with the materials settings.
