as a detailer, i'd say post the pic of the hood. if its just dull and you polished it, you did it wrong.
so there could be 2 answers:
1. you polished wrong
2. its not just faded and dull as you described but its much more
as for the wrapping, imho, carbon fiber would look silly on a jeep... not only cause its fake, but hell...even worse if it was real! why saving 1kg on a carbon fiber hood on a 2tons SUV? but everyone has his taste.
from this picture, it really seems way beyond repair for when it comes to polishing. but it's very hard to tell. i suggest you take it to a detailing shop. let them measure if there is any clearcoat left on that left side on the pic and then they are gonna be able to tell you if it can be wet sanded and polished, or if there is no clearcoat left. means the paint itself is not protected and UV light screwed it up. in that case: sanding the paint down, repaint and add clear of course.
in both cases, its not very expensive. i dont know how detail shops or paint shops form prices at your place, but covering the entire hood in fake carbon fiber could cost even more than polishing or even repainting the whole hood. if it can be polished, it can be done in about 30mins. but it really looks like you have no clearcoat left on that pic.
Don't get rid of that niner grille to put on an ugly chrome one.
Reverse... put in the chrome grill and then sell the niner grill and make some money. The niner grills are in very high demand and you'll make some good money.

I bought the HI-WAY BLASTER HORN that's 139dB and every time I honk the horn an Angel dies.
