Kepler's automotive range is nano-ceramic, which means heat performance comes from the film's construction rather than from how dark it is. For a Tesla, that opens up the lighter shades to owners who want solar performance without changing the look of the car, and it makes the darker shades a style decision rather than the only route to comfort. The right choice depends on your car and how you use it, which is exactly what a dealer will talk through with you.
