I'm looking through some of Koenigseggs work and i'm falling in love with the look of raw carbon fiber. What they are doing is basically sanding and polishing down the thin layer of epoxy to get down to the raw carbon fiber.
I have played around with the idea using resin infusion, but as soon as im getting down to the fibers im breaking and tearing them down and basically ruining the look.
Im also not sure how to deal with UV when you can't use clear coat on top. 
Anyone played around with the idea and got any tips and tricks?

He mentions the finish at 4.50

They are also using pre-preg which is oven cured so it may be a combination of very careful sanding and also the fact the resin will be harder to start with thus its easier to sand without cutting so much so quickly. 

It still looks like the carbon is subsequently coated with something to give the high gloss finish as sanding to the carbon surface would leave it dull - unless it is some uniquely coated raw fabric used in the pre-preg that stops you cutting right into it and hence it can be polished?    Somehow I suspect they won't tell us the exact process!

UV stability is not likely to be an issue.  Carbon itself is fine, its only the resin itself that yellows.  The layer of resin is so thin on most infused and pre-preg parts that when they eventually do yellow, its too thin to see it.  They will also likely be using a modified resin to give improved UV resistance compared to a standard epoxy.
