Tinting the windows on CX-5
 

What is this that's on the windows from the factory? Is it paint, is it film? Does it have any UV protection or heat protection?

In talking with tinting shops I get different info. The least expensive way is to only tint the driver and front passenger windows. But with new tint now you can do more to block heat as well. I'd like my windows to match. But I'm getting different info on what comes on the CX-5 on the back passenger windows and further back.

The glass is dyed. Just tint over it.
