I finally noticed the sticky peel off. It was kinda hard to get off. That's my excuse and I'm sticking to it.
The job turned out well. I did it in the winter, so the air trapped in there is about as dry as I can get it without using the welder argon to try to fill it. I only did the door window for my first attempt. The hardest part of the entire job is getting the old sealant off and cleaned up. If somebody else did that part, I could do these all day long. Ran out of time to do the drivers window, but that is next. Makes a real difference inside and out of the coach.
