Can you buff out a scratch on Carbon Fiber?

No idea how it happened but there are two noticeable scratches on my M Performance CF Trunk Spoiler. They are deep enough to catch with a finger nail. Is it possible to buff this out without damaging the CF? Anybody try this on any CF before??

BMW spoiler? Can you post a photo of the scratches?

I'll try when I get out of work. Just curious but... why would it matter if it's a BMW spoiler or not?

Try Zymol Cleaner Wax (even Wal-Mart carries it) and use it with a micro fiber cloth. Apply in circular motion, then buff off. It should remove (fill) fine scratches and imperfection. There's a clear coat on CF so it should work just fine.

If buffing it out wont work then filling it as suggested by JNoSol would work but will need touch up pretty often.

Use a nice compound and finish it off with a carnauba wax to seal it and restore the shine. Do it by hand at first with a microfiber applicator pad. Depending on how deep the scratch is you should be able to get it out with some work. PM me if you have any more questions.

BMW Spoilers are pre-preg carbon fiber and therefore do not use an aftermarket clear or heavy resin content like some wet lay products. As a result it might be difficult to buff out some imperfections. There is another solution, but would involve having a body shop clear coat the trunk spoiler. If the scratch is not too deep, you might be able to take care of it with some compounds and fillers.
