I purchased the flex paste to close open ends in my deck railing which is 1  1/2" pipe.  your product was fresh and I used a butter knife to do the job.  I was able to clean the knife and my hands afterward ...it worked perfectly and I still have some I am saving for any leaks that should arise.

Buy from Mfg for fresh product and low price

flexsealproducts.com

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!!!

Wonderful Product/Bad Timing

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!

Put on top of our toy hauler

The tub is actually small. On TV it looks large.  The product works great and it sticks to just about anything.  The tub arrives with a foil covering or should i say partially covering the paste. The product not covered will have solidified. I estimate that i lost 25% of the product because of this.  Maybe someone should check when they are making the product that the foil needs to COMPLETELY cover the product

Sticks to everything

It works as described to use under water . But I warn anyone trying to use this product in their Koi fish pond.. Do not use!  I attempted to use this to stop a leaky water skimmer. Although, so far my fish seem unharmed, Flex Paste leaves a large oily film on top of the water. It is virtually impossible to get rid of without fully draining and washing your pond out.

No good for koi ponds!

When I got the jar the outside of the paste was already hardened. About 1" around the jar. I used the inside of the jar and it was ok. I am not good at stuff like this and then I saw the spray kind and that is what I should have ordered to begin with!

The stuff works!

This is a great product..... however, only 3 Stars because I expect to get what I pay for!  I purchased the 6 lb. tub, so I expected to get 6 lbs of usable product.  But when I opened the container I found a dried ring approximately an inch and a half wide and deep around the top of the tub.  I paid for 6 lbs but only received 5 lbs of usable product.  This not the first time either.  I have purchased a total of three of the 6 lb. tubs and three 1 lb. sizes over the last two years and ALL of them have the same issue. So, if you need the amount you paid for you will need to order and pay more or purchase another brand.

Don't Get What You Pay For

When advised on tv you show the three pound tub and a much larger tub but at the website to purchase the larger size isn't available. 
Also in each 3 lb tub that I purchased there was a large dry chunk of the material that I had to remove in order to get to the rest of the paste.

Disappointed

Seal membrane inside bucket only contacted product on 2inches diameter out of 4 5/8” diameter bucket.  Made about 10-20% of bucket unusable because it had hardened into an inch plus thick donut. Tried to patch a crack in wet tar on roof and paste wouldn't stick just rolled up onto other side of putty knife. Worked good on A/C hole in window.

Flex-Paste 3# bucket black

So far I went through 3 tubs out of 4. In each tub, when I lifted out the foil "seal" there was a ring of dried and hardened paste all around the edge which I had to dig out. Seems like the seal did not seal very well,or the product sat around too long. Also I sure wish the paste was a little softer and easier to spread and work with.

Flex Paste

totally failed to live up to what was advertised. i was trying to seal cracks in a fiberglas tub. it didn't stick, just slid across surface as i tried to spread. spent a lot of money on a total failure. i  fixed the problems by using epoxy and fiberglas tape.

flex paste didn't work for me...
