In some states you can tint the border of the windshield, as of uv protection idk google it.
....I never knew that. Thanks .:woot:stick a piece of white paper on one side and look through the glass at the paper. If it's a different shade then you have your answer.
I don't think so.Well I mean does the whole windshield have any kind of coating on it? I have the tint above the windshield.
