I am looking at getting ceramic tinting on my 2020 Model S, I have seen things the Model 3, which I'm not sure if that applies as well. When I went to have the guy look at it, he said the rear window tint would have to be removed, but I saw where the Model X has no tint on the back, it is the glass. Is that the case with the S? I'm not looking at getting colored tint, just clear ceramic. Any help would be appreciated.
