Amazing!

So for 9 years I've been trying to seal my back sun porch which has an aluminum roof. My son and i coated it 4 times, I had a contractor coat it twice and I coated it another 4 times last Spring. But it still leaked and got considerably worse as time went by. I thought, what the h%$l, let's give it a try im running out of options. I sealed the roof prior to a storm so i could get a good test of the seal and NOT 1 DROP! I can't believe it! Although it's only been a month i feel it did the job, time will truly tell but i couldn't be happier.

Wonderful Product/Bad Timing

We purchased this product for some small leaky areas in our house. We had previously used the spray Flex Seal which worked great. However, there were a few areas that needed a long tip to fill in some gaps. Although our purchase had absolutely nothing to do with the Hurricane that was brewing, once we realized the storm would be here sooner than the product I drive around town until I found some to use immediately. We sealed everything we needed but unfortunately nothing could have stopped the force and duration of that storm. We did finally receive the product after the storm and we will definitely use it in the future to reseal all the problem areas once we rebuild that area. This is no reflection on the durability of your product, Mother Nature is just a beast!!!

Flex seal has a new purpose (or two)

Two different uses of the Flexseal paste I have never seen advertised. 1) I have used Flexseal to repair bicycle inner tube punctures rather than a cheap patch. Normal prep of the tube and a coating if the paste is all that's required tor an air tight seal and no issues. As a competitive cyclist, I have lots of training rides in less than ideal conditions resulting in several punctures. I'll usually collect several tubes and spend very few minutes affecting the repairs. 2) I'm currently replacing pool decking and installing composite decking over a concrete and paver pool deck. Over time, the pool deck has shifted and cracked and the surface is uneven and broken in places. I use Flex seal to help anchor the ends of the composite decking to the existing surface to keep the surface level and secure. Works well.
