Great product
4.88 out of 5
Very sticky and adheres well to the existing bottom board. It seams to be pretty tough even though it is thin and flexible.
Works as I expected

Works like it should

Very sticky. I do recommend this size tape & order more than what you think you will need. \r\nTip: Cut your repair area like an X. This makes it easy to mend this area.

Worked as Advertised

Adhesive is very sticky! The tape body was somewhat thinner than I expected, but it sealed up my bottom board tieghtly
Fixed my underboard after duct repairs!
4.88 out of 5
I made the mistake of having a duct cleaning company clean my ducts. I had to have them all replaced. I told the Heating & AC guy I would fix the underboard after he was done to help stave off some of the repair costs. When he was finished I also added additional insulation through his repair cuts. I sealed all the cuts with the Flex-Mend and the underboard looks great.\r\nI also bought the wider Flex-Mend to repair critter damage.
