Skip the bike tube repair kit, and go down to the local automotive tire shop and get a couple of their peel & stick patches and the cleaner that goes with it.
After you make the temporary repair, call Mark at Douthit , 313-244-4037 and ask him for the form to order a replacement blanket, then do it.
I don't know where they get the stuff they use but I am sure it came from Krypton with Superman.
Super flexible, will last next to forever and a day!
