The Ultimate Series window film is a very unique product in the fact that it is a all metal product guaranteed by the manufacturer not to fade or discolor but it is non reflective. Many manufacturers have films that are guaranteed not to fade but they are reflective. It also comes in a unique shade of a 28% light transmission for the man or woman who likes a little bit darker but is still legal. The Ultimate 28 is the most popular window film that we sell. It has a natural grey color modeled after the G15 Ray-Ban lens. It does not distort the environment it only enhances the natural beauty around you. It naturally enhances the color of the window tint that comes from the factory on most vehicles. It is also Houston Tints' owner's personal favorite.
