Is this coating only useful when it comes to types of cars and colors? I have a White car for instance, and I know that white is about the best reflective color when it comes to light we can see. But this coating on a white cars headlamps compared to a black car, is it a waste of money and time or is it beneficial? Just curious and please no bashing, I know this coating is good for the headlamps and license plate, and I am thinking of buying this coating and getting a laser jamming device, as in my area, I am starting to see more use of laser. I think my town just got a bargain on lidar, as I am starting to see these LEO's use it more all of a sudden.
