I was toying with the idea of adding another layer of tint to the panoramic roof since its not very dark from the factory and it might let in too much light and heat in the summer months.
Any added another layer of tint? Any issues doing it, since it slides in and out, would it get scratched? Also, if you have done it, what % did you add, and if you have pics, that would be great. TIA.
