I have that kit too - still in the box and at present I'm just collecting the bits and deciding how to do it. Surely you can buy carbon fibre decal thru' the internet??
There are a couple of made up Enzos on
http://modelersite.com
one of them made professionally I think, both have build reports.
I've heard of spraying thru' mesh and all sorts of ways to get this look but the truth is I've never seen one that looks as good as when the decal is used.
If I were you I would certainly try to get the proper stuff.
The dashboard of the Enzo particularly has two different types of carbon fibre showing. Try and get hold of a copy of CAR mag (current issue) - there is an article on the car in that which has some pretty good detail shots of the interior.
(seats incidently are GREEN leather bolsters on that one).
If you can't get hold of a copy I would be happy to send the pics over the net to you.
Email me if you want them

Best of luck
