I had a couple of badges and some spare carbon wrap; it was a n absolute mission and still didn't look right!
In the end I sanded the chrome part down, sprayed with a grey primer then after a day sprayed it Matt black. Paint was a few £ per tin and job easy to do. Anyway I knackered that badge-hit a deer
so when I replaced the grille I got a black plastic one off the bay for about £15. Quality great and no stone chips in the paint!
