Hi.
Got the same issue on mine 2... I did the metall polish and it looks great for a while then its back to the polish again..
Since black wont match a silver car i'm woundering about Gun Metall grey.. Maybe someone with good skills could do Photoshop of Silver A8/S8 from the side with gun metall grey trims?
Hm...Would 3M Carbon on all that trim be to much F&F ?
