The hinge is doing well. I used a clear epoxy from Home Depot. Sets up pretty quickly so when itd squirted along the channel on one side you're committed to making it work. Hope this helps.
I see you used the H channel style hinge. Did you use adhesive in the channels? Have you found this hinge to hold up. You did a really fine job!! I'm wanting to convert my full windshield into a foldable windshield.
That foam is pipe insulation. You can find it at any hardware store and comes in sizes to fit different sizes of pipes such as water pipes etc under a crawl space or in a hone that needs to be insulated. It comes with a slit already cut in it. There is a film that you pull off to expose the “sticky” and then all you would do is apply it to both sides of the glass.
