The tint shop I plan to use mentioned this as an issue as well. BUT he said he would and could do it but could not discount the price due to the extra precautions/work involved. He is "discounting" all the other tint 15%. If you really want it done someone will do it!
Had my side glass done yesterday. XPEL XR ceramic 70 rear, 35 front. We talked about doing the windshield in the 70, but I'm worried about the effect on the HUD and also using my prescription Maui Jim polarized. He said same thing about the RAM windshield, must take serious precaution with water because of the BCM location.
