I actually bought 1″ foam and black vinyl from JoAnn Fabric this past weekend. My wife is hopefully going to make the glare shield this week so I’ll let you how it turns out. Also, I had responded back to your other post but had another thought on the TV’s. I purchased Vizio’s and although the bottom was flat my wife and son still had to hold them steady until I had the inside and outside walls installed. I’ve attached a picture of the outside wall. I also cut the inside holes too high so I used felt pads on top of the 2×4’s to raise them. Hopefully this helps.
