Anyone with tip on how to go about it? The back is curved, not sure how I can get it on correctly.
You just need to get a strip of vinyl wide enough taking into account that it's curved.
I would apply it wet so you can easily squeegee out any air bubbles,also lets you lift it up again to remove any trapped bits of dirt you might get.
Let it dry out for a bit, then very easy to trim just following the edges of the panel.
The tricky part is getting the vinyl down into the recess bit where the H badge is, you would need to just warm it slightly and work it in around the curved edges, would also mean removing the H badge.
While your at it, you should do the numberplate area black as well.
..........Ooops! just realised your thinking of carbon wrapping it...same as above tho, only you wouldn't apply it wet, just use a good carbon vinyl that has air release channels in the adhesive.
