Somewhere in some BMW book ( I think in the Bentley Enthusiast's Companion)
there was an article regarding the use of spargplug wires to replace the
plastic chrome trim. Maybe that's the way to go. You'd have blacked-out
rubber. That may actually look cool.

BTW your qestion was not too clear. I'm assuming that you're referring to the
plastic trim and not the "windshield gasket" as you refer on the subject
line. Correct me if I'm wrong.
