Flex Seal Reviews 

Total crap ! Paid $30 for flex tape today ! Says it stops a leak instantly! TV adds are also false advertising ! ACE hardware won't refund my money ! Terrible product!

Your product sucks, I have put three coats on a leak and it's still leaking, it's pathetic

I tried the tape on my pool wall. I had a cut in liner. The top would stick where thier wasn't any water. The bottom part where the water line was it didn't even come close to sticking. The advertisements are very miss leading to the point of lying. Don't waste your time or money.

Tried to seal a small concrete pond with no obvious cracks or holes...ended up using 3 containers to make sure it was very well coated....leaked like a sieve this crap did nothing DO NOT BUY

I have never used flex seal personally, but I really distrust Phil Swift when he does these TV commercials for Flex Seal.

As a consumer, you have to have a certain level of trust both in the person doing the commercial as well as in the product itself.

My level of trust in him and his presentation skills and his product (Flex Seal) would be about a 1 out of 10.

He is always smiling throughout his commercials which strikes me as not being very genuine; it is ok to smile every so often but doing it throughout the commercial makes him come across as not being honest and genuine.

The other thing that "turns me off" about his commercials is that he will do some really wacky things like putting holes in the bottom of an aluminum boat and patching the holes with Flex Seal tape. Then you see him driving this boat across a small lake and waving at the camera!

Anyhow, when I see him doing these silly and outrageous Flex Seal commercials, I usually mute the volume or change the channel.

I have purchased & used 3 of your products.
I found all falling way short of expectations... simply sealing side windows on camper shell. Waste of money.
O stars.

I brought this product to spray on my PVC pipes under my bathroom cabinet and kitchen cabinets. It says and they advertise that it does stop leaks, any leaks that is not true. I never stop the leaks if I could have gave it a negative star I would

Watching the commercial for the boat being pierced. He is riding the boat afterwards, yet there is NO fuel tak in the boat. AI..... FAKE!

Avoid for any job with an uneven surface. Had a leak to temporarily repair, PVC 1.5 to 2 inch pipe pressure side of a pool pump that failed to seal with this tape. At over $14 it was a waste of money. The tape is plenty sticky, so much so that I wasted half the roll trying to get it in place. Cutting the tape is difficult, if not impossible and the tape sticks to the scissors and everything else it touches. For a flat surface that does not require much tape cutting you may want to try.

followed directions for application of flex seal liquid. This coat and after 3 days still wet. Area where flex seal has been applied to is ruined. Stay away from this product.

Wish I would have read the reviews first, bought the spray for a small leak on my gutter seams. It came out like water. Let it dry put two more coats on... it actually leaked worse.. Then if I wasn't dumb enough I bought the paste.. scraped and sanded and put the paste on.. all I can say is they saw me coming. Terrible product

Flex Seal liquid will fall into cracks, therefore NO SEAL! Flex Seal tape doesn't adhere to Flex Seal liquid, after 3 days of letting Flex Seal liquid curing.
SUCKS!!!

worst product spent 17 dollars for a dried up tub of junk

This stuff was so bad its nearly comical. I could have tied a rag around the hose and it worked as well. 1 star is too high for this. Use only if you are prepared for disappointment.

Not a good solution for fixing roof leaks.
It will eventually cease to adhere to the roof

Purchased two tins of Flex Paste to seal a minor leak in a concrete water tank. Is supposed to set even underwater, but it wouldn’t stick at all. Apparently it cannot do what it claims.

I bought this product because i found a small hole at the tip of my condom..i thought the hole was leak proof..two weeks later my girlfriend came up to me and said shes pregnate. Good one flex seal🤬 your product has given me a life time of misery..

Bought flex seal draft tape---Good concept but does not stick. Bad adhesive negates a great idea. All of the ends started curling right after application so when it gets below zero this winter I am sure that it will all be in the trash can,

Well I bought flex seal twice both times it was bad you can't seem to make a good product waste of my time to bye it again i will give your product a subzero

Not a durable fix for even minor RV roof leak.
It might of lasted a month at the most.
Don't waste your time and risk having another leak, it is not at all dependable.
