Reason why I started this thread. My buddy's CGT started to yellow --- sucks to see on such a nice car.

Sucks to hear that, but its supposedly quite common on the Carrerra GT, visible within 3 years. I think alot of the yellowing you saw with Porsche was the resin turning yellow. I believe, though I'm probably wrong, that some manufacturers now place uv inhibitors in the cf resin. interesting link re: cf yellowing and resins http://www.oppracing.com/opp_pages.p...rbon_fiber_101

yes factory OEM spoiler. Clearcoat layer went first and then the yellowing...

like what I said, it could be redone, but it's a PITA and it'll take well over a week considering it's a large panel for you roofs.
