hey, what about installing a nano carbon strip of film? or the whole windshield. they are well known by deflecting heat. they come in 100% clear for the front windshield.Once mine is replaced I am going to 1) add the protection film again, 2) Not use the defrost when letting the Gren warm up/sit for any period of time. 3) Considering 3D printing a deflector to sit on top of the defrost vents and slightly deflect the flow straight up so the bottom edge of the windshield isn't getting roasted.
