Flex Tape, 8 in x 5 ft, Gray, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor Projects - Home RV Roof Plumbing and Pool Repairs

Used to patch a seat that had lost some of its cover material. Made a mistake and touched some of the backing against itself. The adhesive is so strong I could not get it apart. It sticks,

Used it to patch a hole in a raft. Very sticky. Stays on u set water

Love the adhesion properties of the tape but I had difficulty removing the film over the the tape on one of the rolls. Returned & waiting to apply the replacement

Used on boat. Worked great.

Just Ok. Seems to do a better job of sticking to itself than anything else.

We use us to help protect our house from hurricane Milton. We were very careful with how we applied it. Driving rain got through. Pulling it off of the front door took off the finish.

Although I haven’t used this particular Flex Seal product yet, I have used some of their products. I purchased this product as part of my emergency kit for my boat. I had another captain recommend this as an emergency fix just in case a “through hull fitting” breaks or starts to leak. Flex Seal Tape works under water so if a fitting breaks off or a leak appears while out at sea this tape can be applied as a temporary repair until you can get to port and do a more permanent repair. This could save your boat and possibly your life!

We peeled off and cleaned any old sticky stuff from previous attempts to seal and ensured it would have good adhesion. It has been 8 months and so far, the shed hasn't leaked. I am curious as to how well this will hold up in the full sun but so far so good! Pliable, easy to cut, and once it sticks, it is hard to pull it up. So, make sure you put it where you want it!
