Mine's CF add on wing

[FairladyZ10PG]

First I could not be any more disappointed in the workmanship of the Mine's CF wing.
When it first arrived, the inner edges were very roughly cut and they didn't even bother to put clear coat on it. It also had scratches and bubbles. I waited over 2 months to get these and I wasn't going to wait another 2 months to get this one replaced so I just decided to keep it. It's been a little over 2 months since the purchase and it has started to form a haze on the inner parts of the wing. Is this something that can be fixed or should I have them replace this? You can clearly see the white part where they didn't clearcoat... I'm afraid that the haze will only get worse.
