Title: Fantastic Tape for Dryer Vent Duct
Review: I originally purchased the 3M 2113NA High Temperature Flue Tape to wrap around the connections on my dryer flexible vent hose. That was like wrapping the vent hose with aluminum foil - there practically was no adhesive. Whatever adhesive was left was on the subsequent layers of the tape. I knew I had to get something else to wrap my dryer vent hose, because this was not holding. I read the reviews and ordered the Scotch Aluminum foil tape 3311 and what a difference! This tape is superior because each layer has a protective paper which peels off easy. After making the mistake of cutting then peeling, I learned to keep the protective paper on just a little bit while wrapping the tape around the duct and that worked perfectly. I actually removed the 3M 2113NA tape and re-wrapped the entire duct in this stuff. Don't bother with the 3M 2113NA and get the Scotch 3311 tape.
