Well my normal level of luck finally caught up with me. Was installing the glass panels today. Got the front installed and was installing a side panel. Took a lunch break and heard a loud pop. The side panel broke. Some how I over looked a spot where epoxy had made a droplet. Well I just happen to have my clamp on that very spot. I've gonna ahead and removed the front pane. Gonna go over all the glass mounting surfaces with a palm sander. Like I did all the first 5 coats. Expensive lesson learned.
