Jonnycool,
While at the SEMA show last October, I was introduced to a stick-on real carbon fiber sheet. I tested the sheet on a garbage can and sprayed it with multiple coasts of Krylon Clear Coat. While it was real carbon fiber, I couldn't get the smooth glossy look you get with purchased carbon fiber parts. A friend told me to try and coat it with an epoxy type of liquid, but I haven't tried.
Take a look at

Good Luck
