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 Paste Works
It does all it says it can do. I have had leaky skylights for over a year and have tried various ways to stop the leak. Need I say more? Flex Paste sealed them up. I am going to get two more tubs of it, just to even out the job, now that the first application has set.
The skies the limit when it comes to everyday things Flex Seal Paste can help with! We're so happy to hear you were finally able to succeed in plugging up that leak. If there is anything we could assist you with further message us through Humans@flexsealproducts.com. Have a flextastic year and Flex On!

Put on top of our toy hauler
We put it on top of our toy hauler which had leaked the previous year. It was a chore prepping it and our friend who lives in it did a fantastic job painting wherever there was a possibility of water seeping in. Two days after competition we had a big, long storm, and all is well! I was worried about my friend and my nice toy hauler, but all is well!
