I have had it on black X5 before. Is not noticeable till you come close, but was noticeable when the car is dirty. These days they cover the whole hood so you never see any lines, even if dirty. Suggest doing it sooner the better. Apart from full front and headlights I also did door sills, door edges, back of door handles(ladies nails scratch there) and rear bumper top. Just have to tape nicely when polishing car otherwise wax settles next to film edges and difficult to get rid of.
