Worked Great To Seal a Rubbermaid Shed Roof
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!

Great tape, better on dry surfaces
This tape is great. But i had better luck when surfaces were absolutely dry. Give it a day to seal well. I used it on one corner of my pool due to it being a bit lower after filling. The gray matches my pool! Holds up well.

Life Saver
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!

It sticks!
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,
