Is this fixable/repairable?

I have a pair of "Future Design" CF replacement mirrors. Last week I noticed that the Carbon looks cloudy/foggy. Is there anything I can do to fix this?

This looks like the sort of haziness that often appears on older headlights with polycarbonate lenses. I have had good luck restoring those the Chemical Guys compounds (V32-V38) on polishing pads on a random-orbital machine, but probably any fine rubbing compound would do. Of course, try a test patch in the most inconspicuous spot to make sure you don't cut through to the color layer.

I've had decent luck with wetsanding and polishing on something like this, but who knows if this part has already had that done to it. You risk sanding through the clear. Unless you have decent knowledge of wetsanding/polishing (or the tools to do it) you might be better off just going to a body shop that does work for dealerships (mobile or retail shop) and asking them what they would charge you to re-clear those. In my opinion, that would be the easiest way to get good results. Again, that's IF you do not have the tools/know-how to wetsand/polish.

That's good advice right there as you are correct, OP has no idea how much clear is there to work with

However, before you spend money on a body shop repair, first try polishing like others have suggested. Go with a Menzerna polish like SF4800 and a coarse hand polishing pad and it should come right back.

If not, use my guide here to re-clear and wet sand yourself.

Those parts are about as easy as it gets to paint. Just ignore everything in the guide before the clear coating stage and you'll fix that for around 10 bucks

Your rattle can write-up would be a good option for this for sure! I hadn't seen that one yet!

I had a trunk spoiler which had a similar issue, the thing about carbon fiber is that there is two layers of "clear" there is the actual clearcoat and the epoxy resin. I'd use a polish first to see if that helps it out, if not try wet sanding going from 1000 grit > 1500 > 2000 > 3000
if those don't work, buy a can of 2K CLEAR, make sure it's the 2k kind as that is what will not only give you high gloss but also a weather resistant and durable clear coat
This is what I used :
