This is a sample of our "3M Black Vinyl" option for back windows of vehicles that have the wide black "Dot Matrix" at the top edge of the rear window. Many new models have it, and most window films will not adhere well to those dots in this area, leaving the back window looking pretty unprofessionally tinted if the film is mounted over these dots. This Black Vinyl Overlay option runs about $40 additional, but lays very well over the dots and cleans up that top dotted area very well, making it completely blacked out and looking very finished. A very good option for the discerning auto-enthusiast.
