While most other window film companies buy their polyester from someone else, 3M makes its own polyester in Decatur, Alabama. During this process, 3M patented a technology for producing its own nano-carbon polyester. This revolutionary and unique process, allows for maximum heat rejection without metals, which can interfere with radio and/or satellite signals. It also gives our films a beautiful neutral black look with unpararell color stability. Never before has anyone done this. In fact, it's so advanced that in time-based tests, 3M Color-Stable Auto Film held its color while most conventional dyed films rapidly changed to a purple color. No purple windows. Guaranteed!

We stand behind our work. Color-Stable films are backed by a limited lifetime warranty, which includes color stability.

Look for the 3M print mark on Color-Stable films, it is your assurance of authenticity. You know that your car features authentic 3M Color-Stable Auto Film when you see the 3M print mark on the window itself.
