I use these on our youngest‘ windows. You can cut them to measure, attach the sticky patches and you‘re done. Works very well. One side black, one side silver.Solarscreens came back to me saying I would need to make templates for the IG windows so they could make the window covers. I pointed out this thread and suggested they already have them! As the windows on the Prototype are the same as the production vehicle, plus or minus safari windows.
Now waiting for a response.
