Interesting.I did it on my last car, but don’t have a sunroof on the ram. I used 80% ceramic tint and 4% on the rest of the windows (excluding front). It worked great to keep the car cool when it was running, but I also felt like it kept the car hot when parked.
It could just be me and the 3m tint I used, so it would be interesting to see what others have to say.Interesting.

The ceramic is literal night and day difference in temperature. I'll never go back to regular tint for vehicles.I had 20% film added to my sunroof, not ceramic. I guess it helps. Always have the sunshade open and my A/C works great.
