Esanger, no more coffee find the hardware locally, its not heavywater or anything. You'll have tons of piece parts before you are through with the hobby. I would imagine the covering should simply be trimmed away of the fin's slot and glue joint-not uncommon. Use a heat gun to carefully shrink the bubbling covering (I use a wagner powerstripper on LOW), it will be good as new. Enjoy your baby. Don't rush if you can help it. It won't fly itself, it won't build itself. Good luck.
