I remember some POS Eunos Roadster off the boat from Japan at Mototec in Dublin; the previous owner had blinged it up with KG Works rubbish, and then methodically covered the windscreen surround with black electrical tape. From a distance it looked ok, but close up, it looked like the worked of demented 16 year old.
Easy cheap and good looking mod IMHO.
One can do this simply with a Rustoleum satin black spray can for metals (about $3) and some very careful masking. This paint takes a little bit to cure but once it does its very durable and cleans easily unlike flat black. Satin black also looks better then either gloss or flat. The same paint is also good for the rocker panel area.
You know what's kind of annoying? I've never seen a black header on anything other than Mariner Blue, Classic Red, Velocity Red, either White color, or Black. I wonder what it looks like on other colors, when the contrast isn't as good.
I have to admit, i like how this looks so i did mine today with black vinyl as well. I have never used the stuff before, it's tricky around curves and stuff. I think it came out ok, definitely not a professional result, but I wanted to see what it looks like and right now I really like it. Here is a crappy cell phone pic:
