What is the dot-matrix?
The dot-matrix is a series of dots or lines along the edge of a single piece of glass. Most frequently, it will be found along the outer edge of your rear window. These dots are made of a teflon material and are used to various reasons, one being…”just because”. Regardless of why certain car manufacturers insist on using dot-matrix on their glass, the end result after tinting can be unpleasing, to some.
What happens when tint is applied over the dot-matrix?
Window films are designed to adhere directly to glass. Once window films are properly installed to a smooth glass surface, you achieve the beautiful and elegant look of a window film. Since the dot-matrix interrupts this smooth surface, the area around the dot-matrix can and will take on an unusual look. We’ve heard people describe it as, peeling, silvery, faded, rocky mountains, and just plain white.
What can be done?
Overall, not much. Some have had luck with various techniques to diminish the appearance, this includes: applying alternate adhesive, cutting around, vinyl, sanding the dots, and paint. No one technique is 100% effective, 100% of the time or looks any better. In the long run in our experience, a lot of time can go into trying to make the dot-matrix area look better, without really making it look better. The best result in our opinion, is to allow the film to adhere naturally to the dots and surrounding areas. If you are very concerned, be sure to communicate with your installer prior to appointment or film application.
