There is a reason so many cars on the road have purple windows and bubbling rear glass: dyed film. It is cheap, it goes dark, and it dies in the Colorado sun. Carbon is a step up and still not what we are willing to put our name on.
Nano-ceramic film uses ceramic particles rather than dye or metal. It rejects infrared heat, blocks over 99% of UV, resists fading and purpling, and never interferes with electronics. That is why it is the only category we stock.
Film is only half of it. Every install is done in a controlled bay with computer-cut patterns where available, hand-shrunk glass where it isn't, and a clean-glass process that keeps contamination out of the finished edge. Then it's backed for the lifetime of the vehicle.
