Thank you for your help.I have covered the bottom half or top half of several store front windows and never had any problems and I also have a solid 8-9" wide black strip across the top of the windshield on my truck with no problems. I have had the strip on my truck for 3-4 years now. I did have a customer with a truck, paint the inside of his back glass...He had a wall full of speakers so he couldn't see out anyway and just wanted to hide the back side. As far as I know he didn't have an issue.
I didn't think it was a good idea either.
