Unfortunately, upon opening the plastic container, only half was usable as the outer sides of the container were hard and unusable. So, As much as I Love this product,, because of the price, and I only could use half of my purchase , I will not buy again.

I purchased this Flex Seal and then a week later purchased another one. I went to go use them today and they are both dried up and unusable. Don't waste your time or money.

I was worried bjt, it worked I repaired a fiberglass bathtub, it was thick, I globed it on and to worked good, my can was air tight and fresh, not permanent but long lasting patch, don't get it on your clothes,,,

Worked great to fix my leak. unfortunately the product must have a shelf life. When I first opened it, peeled off the protective cover, , about 1/4 inch from the edge was already hard. There was enough in the center for my project. Glad I didn't need to whole can.

I'd have returned this product if time had allowed.The top 1" was rock hard and completely dried out.I had to break through the top layer to get to usable product.It did stop the leak.I'd have given 5 stars if 1/4 of the product wasn't dried out.

This stuff works great. Used it to seal some cracks in a basement wall where I had water coming in. The only thing I didn’t like is the can it’s put in. It’s hard getting out the material because of the lip for the lid. Previous version I used was in a plastic container and it was much easier to remove the material from the container. Otherwise this stuff works really well.

Perfectly seals

UPDATE - I have been monitoring the pipe for the last few days. While I initially thought the paste was going to provide the fix I needed, that "thought" would be incorrect. The water started leaking again. Be smart/save your money and do not buy this stuff. I'm going back to what I should have done to start with - turn off the water and replace the pipe. This Flex Paste is JUNK!!!!Had a very small leak at the base of this water faucet (small droplets of water on the PVC surface). Based on the advertisement I thought the paste would be the perfect fix. I followed the directions as stated on the container. After apply a good initial coat, I still had the small leak. The next day, I applied another coat - still had the leak. The next day, after turning off the water to everything, I applied another coat heavy/massive amount of paste using both a putty knife and my hand. Left the water off for 1 to 2 hours and the leak appears to have stopped (after using most of the paste). What a pain!!!While using the paste, I was diligent in keeping the lid on the paste. At the end of each day, I would use a rubber mallet to hammer the lid on. Regardless of the tight seal, the paste still hardened.Probably would have been easier to just replace the bad piece of PVC that was leaking.
