Tonight I was trying an old trick I used when we used to use wheat grain bulbs for lighting our planes. i would pull the foiled paper out of my cigarette packs and CA it to the back area where the bulbs go. This created a reflector so light wasn't wasted going into the plane. Works on DTFB too! I tested it on a couple of scrap chunks. Gorilla Super Glue. It also (discovered by accident) hardens and seals the edges as well as hot glue, without being... rubbery. On a second piece I gently wiped the edge with a smaller scrap chunk like when you use hot glue. I rolled the edge a touch. It held, and didn't wrinkle the paper. With a gentle hand I rolled/pushed both edges before it dried, and it created a nice somewhat curved edge! I'm thinking of using this method on my exposed edges on my two birds.
