No experience with carbon fiber, but for wood I'll sometimes *gently* polish with abrasive products if the scratches are truly bothering me. Gotta be careful though, the finish on interior wood can be thin/fragile. I don't like to get more aggressive than the old 3M PI-III MG 05937, but I *have* used harsher stuff a few times.
KAIO works OK but doesn't correct, or hide, defects the way some other products will. I'd be leery of the abrasives in ZAIO based on how they behave on exterior plastic. I would *not* use M205 for this for the same reason.
Most of the time I use something like Autoglym SRP or 1Z WPS to clean, conceal, and protect in one step.
Heh heh, on the Jag, I'm still using finishing up with my tiny jar of Zymol's interior wood wax (relabeled for the old BHMA store, the Zymol name was "Detail") from '85, with a cap that cracked in '86, and it's still working fine. It's basically a cleaner wax, seems very high in carnauba as it feels gritty until it melts a little.
To be perfectly honest, I don't get as worked up about the condition of my interior wood as I used to. Not that it gets *bad* or anything...but it's far from perfect if you inspect it carefully in the right light
What can you do :nixweiss there's only so much clear on there and if you polish every year you'll end up having to refinish it.
I don't try to correct marring on interior aluminum. In my vehicles it's clearcoated/clear anodized/something and I don't want to compromise that finish. So I just try not to mar it in the first place (like with the wood) and occasionally clean it up/protect it with something like KAIO. But that's a very occasional thing....I hardly ever bother with it.
Most of the time a quick spritz of something like Meguiar's Interior QD is all I bother with, at least on the drivers.
