Can anyone give a definitive answer on weather the Solar Glass on my Soul's windshield has UV protection, and if so, what percentage? I can't find info on UV protection on this stock factory glass. I'll be parking in the sun a lot this summer and want to protect the dash and interior as much as possible. My tinting on the windows and rear glass have UV protection. Dealership couldn't't give me the answer on the windshield. Thanks!
