    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.

    4.0 out of 5 stars Leprechaun-Free Flex Paste: Great for Sealing, Not for Mermaids!

    J. · August 1, 2024

    If you believe in leprechauns, then you'll believe Flex Paste works on wet surfaces. But let's be real—leprechauns aren't sealing your roof leaks. Despite its mythical claims about underwater usage, this stuff is fantastic for sealing large gaps and cracks (on dry land).I used Flex Paste as a pond liner seam seal after properly prepping, cleaning, and drying the area. Once it was ready, this magical black goo did an incredible job! No more leaks, and my pond is now a happy home for my fishy friends. Just don't try to use it underwater unless you're looking to meet some imaginary creatures.For dry surface fixes, Flex Paste is your go-to hero! For wet surfaces, stick to fairy tales.

    1.0 out of 5 stars Does NOT work as advertised!!!

    C.S. · October 28, 2024

    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.

    I have used Flex Seal paste in household projects over the past few years and had extreme success. Over the past month I removed cleaned and reseated 14 Portlights, and 4 Deck hatches on my sailboat. I have full confidence that this will last long into the future. The price was a 50% of the previous 3m products I have used in the past. It may be over kill but I used 12 tubes for my project. I used the RYOBI battery powered caulking gun, which made it very easy and controllable. I then used my fingertip (rubber gloves) for smoothing. I continually sprayed my gloved fingertip with alcohol and smoothed to a perfect finish.NOTE: I took the above pictures before trimming and smoothing the Flex Paste.

    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.

    5.0 out of 5 stars Used a battery operated caulking gun

    A battery operated caulking gun is a must.
