Excellent product... I live in Florida where it rains slot. I have been living in a camper since my home was destroyed by a Cat 5 Hurricane... The roof of the camper leaked when it rained. I was in Dollar General and spotted a can of Mr. Swift's flex seal and thought why not... I sprayed the entire top of the camper with it and waited for the next storm...When it it hit, it was ferocious! But not a single leak in my little camper... EXCELLENT PRODUCT!

Put the tube in my caulk gun. Almost broke my wrist trying to get glue out.
I'll never buy your products again. $16.00 for a tube of trash
I have a motor home and was interested in using in case of leaks. I ordered a can from Amazon and left in the RV. 3 months later I found the can leaked at the bottom. I was not sure if other cans might have put pressure on the Flex Seal can so I threw it out. I reorder another can carefully checking the date but this time I wappedin rag even a box. The same thing happened. I have photos
Calling the company they did not offer to even replace the can even saying I have photos. They wanted me to send the can back on my own dime and they the would investigate. I said how about paying postage and replacing they said maybe after evaluation.
I have used dozens of products in my RV over the years and never had a failure.
Not sure if it is a good product but customer service sucks and will never by again.
I could not return to Amazon because it was over 30 days
Tip for consumers:
Disappointed with company with something so simple. We were on a 3 month RV trip and could not run around sending things. At the time I had a receipt but after no response I tossed it. You would think the photos would be enough and I did not want to send a package that could still leak

Great product with one major flaw…cannot be stored. Once opened begins to set! One quart can of Liquid FS, used small amount, closed can (just like a paint can) two weeks later top inch was a 'rubber puck'! Carved through that, used a little sealed in a zip lock and refrigerator. Two weeks later opened…top inch was another 'rubber puck'. Tried painting FLEX SEAL around the rim to seal the can…two weeks later the final amount was solid rubber. BOTTOM LINE: you have to use it all once the can is opened.

Purchased the tape that is advertised to work underwater. Tried to patch a small leak on the outside of a 40 gallon plastic tank and it would not seal the leak. Used an 8 foot roll trying to make it work. Don't waste your money.

Not only is this product overpriced, it's totally worthless. After a year, it cracks and leaks. Tried Flex Seal liquid on a roof seam two years in a row, and got the same horrible results. Don't waste your money!

I purchased the Flex Seal White Paste, to fix a rather small leak in the upper part of my 35"X 45" window. After I opened the container, I noticed most of the paste had ALREADY HARDENED INSIDE THE CONTAINER. What was still soft inside the container was very rubbery and quite difficult to "spread evenly" as per the instructions. The result was just a mess. NOTHING LIKE THE ADS FOR THIS STUFF ON TV! These folks outta be sued for false advertising...

I was "suckered in" by the ads on TV. Don't believe the hype...

I am a self sufficient small farm guy. Last night i got my sprayer out from a winter storage that was heated. I proceeded to to put a herbicide and water mix in the tank when I noticed fluid running out the end. After accessing found the seam had split about 7" worth. I looked for my flex seal tape but was out. I then remembered I had flex seal caulking so took the Chance that it would hold and not waste more product. It saved the day and I just wanted to say thank you for a product that I feel lives to its name! I also used flex seal tape after welding two connex containers together two years ago and still no leaks. Thanks again

I used Flex Seal Liquid over waterproofing cement, 3 coats over two days, min 8 hours between coats, allowed to cure for one week to waterproof my small pond. About two months later, I drained the pond to repair the pump to find that the Flex Seal had failed. It had blistered and was peeling. Seems unsuitable for waterproofing application when submerged under water. Advertising led me to believe otherwise.

I would have been better off using Elmers glue. This product is useless. Very runny when you spray and does not secure a leak. I have used the paste in the past and it does not perform or spread as show on TV.
I have purchased almost all the stupid products advertised by this company. DO NOT WASTE YOUR MONEY! Nothing works!Not even for 5 minutes. They have no guarantees but worse it solves no problems. Leaks still leak and the advertising is outrageous lies. Cant say enough negative remarks about this totally useless product line.No need to send pictures just water leaking all over. They should be reviewed by consumer affairs committee and shut down!

DO NOT ORDER_ IT IS USELESS

I went to Lowe's for a 3 pound container of Flex Seal! Upon opening, I got one pound of Flex Seal! The other 2 pounds was cured rubber! Lowes refunded me the $34.98! I received a store credit and got another 3 pound container! Went home and I got 2 pounds of the product! Screw it! The Flex Seal spray cans are better for small jobs!

Sprayed flexseal on last August and look at it today. The crap is not sealing anymore, all cracked and disappearing. What a disappointment.
Could not seal my 8" pvc irrigation pipe this morning. Tried 3 times, scuffed up the pipe as well and it does not stick under water OR UNDER ANY CIRCUMSTANCE'S as shown in the commercials. The pipe is not fixed and is still leaking. Good thing it was purchased at Walmart as they do take everything back and I will be returning this bogus product today. My duck tape works just fine under an emergency. Do not waste your money.

The first 3 inches of tape was very good, then after that, the rest of the roll OBVIOUSLY BAD. Masking tape is better. I used it on the exact same type of area on 2 items (cap area on a paintball bunker). The first one was great. I could barely get my fingers off the the tape. THen, 3 inches into the roll, only about 20% of stickiness that the first 3 inches had. FlexSeal cheats on manufacturing. Gives you the real product for your first little strip then cheats on the rest. HORRIBLE.
Wasted my hard earned money on a product that would take gallons and gallons and gallons in spray form to do a very small amount this product didn't even fill 3/16 inch holes. Don't waste your time and money folks! Great sales pitch for us suckers used a $15 can on this small project and multiple coats with proper time to dry so I don't wanna hear it! Congratulations on yet taking someone else's money with a misleading sales pitch.

I bought the 5' roll of clear flex seal tape and was going to fix a small spot on the bottom of my boat and I even cleaned the area really good let it dry overnight applied the tape it looked to be stuck good and seal off put the boat in the water the next day and the tape peeled loose in several places and was leaking glad I caught it when I did would have sunk my boat
In other words I would not waste my money on this product it is misleading that it will fix boats
Small drips from the end of the corrugated roof line that i underlapped another short sheet on my pergola to make the roof length.
Sprayed and pasted Flex Seal over the underlap joint with the paste to seal and then 2 full cans of Flex Seal spray over total area to cover any open spot.
Dried till nxt rain.
Not even a heavy rain and now the leak(s) have expanded across the entire patio roof line.
How after sealing the leak, the water went against gravity and went under the corrugated roof.
The entire area 8" x 72" was covered by FLEX SEAL and now it leaks even more.
WTF! GO FIGURE... but ill never trust this product anymore and my customers too.

I used it on air filled inflatables with a small leak, does not seal hole and months later still wet to the touch and come off in hands and anything it touches. Terrible product, stay away!
I had a small leak in camper roof. I used liquid Flex Seal and covered entire area 3 feet around hole, Looked great. Next year I decided to coat entire roof. Bad idea. 2 years later Flex Seal starting flaking off and roof leaked resulting in major damage. Also roof cannot be coated with anything until all the Flex Seal is removed. Decided to scrap My camper valued at 6000.00

Applied 3 light coat.let dry 24 hours between...white colour was a good match...saved me lots of $
Opened the container to find a hardened ring of product. Contacted customer service to be told that they overfill the container so there is expected to be some hardening, was told to send a picture and if they thought it was excessive they would address it. Didn't get a response so I guess this is to be expected when buying Flex Seal Paste.
I have used flex seal in the past with no good results. Just used the flex seal tape with even worst results on a simple hose that had a small leak and it still leaked even more. When they show a leak running from a pipe and put tape on and stop. But what I think is they turn the water off. I will let people how bad the product really is. I would post a picture but didn't want to crawl back under the commercial washer.

How can any company or person sell bull crap and get away with it. For instance that bullcrap supposed to plug holes in boats yeah right u will drown. I'm so sick of all these fake bull crap. I really hate ppl taking advantage of other ppl for the sake of money. Wow get a real freaking job. Also they know that ppl gonna buy it at least once and just millions of ppl buying it to see if it's legit these greedy as ppl or company already made millions because we trusted what they say. These ppl need to be locked up and throw the freaking key away! So freaking unreal how they can get away with this.
