Did a little clean up of me bikes, the one advantage of everything matte black is any scratch can be quickly camouflaged with a q-tip full of matte black paint from a spray can.
It will need some sanding and patching and proper care at some point but for visual experience - this is all fine.
Don't know how it would go with carbon but I bet you can get a nice tutorial how to gently sand off the flaky few micrometers and have it pristine for a quick spray up.
