Jim, they are probably wondering at Horizon what the heck is going on with the covering issue. I called and left my number. I got a phone call about 10;30 this morning and talked with a tech. He said there is backing material on the covering. Well, I went down to the shop and had a fight with the end of the roll. If you put tape on the front and the back and peel from the edge, you will be surprised. There is a backing sheet. It is very thin, and as clear as glass. Much thanks for your effort!
