I can shed some light on this..... the Huper Optik is a film with metalic compounds in it that help block out the suns IR. For the most part, the glass on your windows block a lot of the UV rays coming from the sun, however it is the IR that passes through and heats up your car. This film is designed to block the IR from passing through your windows and keep the inside from heating up. 3M has a non-metalic IR blocking film also, that will not screw up your navigation and radio reception, however it is currently only offered to car manufacters and not as an after market product.....
