+x+x+x+xthis looks more like you had a bit of a void in the part or bridging and have just sanded out the bubble, I would mix up some resin again and apply to the local area.
Let it cure and then sand back.
Ok so is there a way to replace the missing bits of weave or is that a no go?
yeah looks like you had a void underneath and sanded trough the carbon. your best bet would probably be to laminate a patch on top of it which will be structurally sound, but visible. for a cosmetic part you can maybe increase the size of the patch and have the cut line on a ledge, where it's way less visible.
Ok, it's quite a large part with minimal edges so I'm not sure if there's a clean way to join it as I'm guessing any join lines would show?
When you put a patch on top try to align the weave which will help to somewhat reduce the visibility...
