I am interested in installing a Pace Car rear spoiler on my 78. However, I would like to be or look like Carbon Fiber. I have installed a similar spoiler on my C5 that actually is Carbon Fiber. This will be like a style statement for my cars. I cannot find any manufacturers of the Pace Car spoiler in Carbon, but I would be willing to have a fiberglass version hydro dipped if that is the only solution below paying for a one off design. 

Anyone know of hydro dipping services for such a large item?

Another possibility would be to see if there is a paint protection film that looks like carbon fiber.  You could check with XPEL and see if they offer it. There's also what they call carbon flash paint. But I don't know if that looks exactly like carbon fiber or not.

You could have it wrapped in carbon fiber looking wrap.

The local installer of XPEL PPF was closed but there is a carbon fiber film available. Just have to Google carbon fiber paint protection film and it'll show the options.
