I plastidip the grille frame this Saturday, gave it 4 layers. Lets hope it doesn't come off that easily.
The spraywrap held on quite good in the beginning, but 1 treatment with a good pressure washer and a few bits started coming off. I just kept washing the car and it got worse. So I decided to do it properly. Didn't even have to disassemble the grille, the wrapper could do it while everything was mounted.
