............Dave, as mentioned by op, Eternabond tape, but if not readily available, I'm sure you have a WalMart close to you, some gorilla tape may not look good but will get you buy until permanent installation. Once you start the permanent replacement, don't forget the "BUTYL TAPE" under the new SKYLIGHT, makes for a perfect seal. Good luck, travel safe.
