I agree with you on the chrome trim on the top, up until I was looking at a custom build featured in Modern Rodding of a custom '36 Ford roadster. I noticed how they had detailed the top on the 1:1 car. I guess the metal usually used in these applications surrounding the rear window and fasteners are covered with the tops exterior material. After seeing how they did the detailing in chrome I thought I would try it, and I like it.
