3M is a leader in creating technologically-advanced window films. 3M's latest achievement is the creation of premium Color-Stable automotive window films that hold their color, are high heat rejecting and don't interfere with your satellite signals. All Color-Stable films come with a limited lifetime warranty, which includes color stability. No purple windows. Guaranteed!

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 unpararelled 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:

• Color Stable is non metal so it doesn't interfere with radio reception and cell phones.
• If you are planning on keeping your car for 5 years plus, Color Stable will not ever fade.
• 3M has been in business for 108 years, with a very strong lifetime warranty, and they are not going anywhere.
• Color Stable is the best looking and best performing film out there.
• If you ever see a car with purple and bubbly tint, it is not 3M Color Stable film.
• Color Stable's logos are printed right on the film for proof of authenticity.
