This toilets' poor design has top and bottom pieces that are mounted together with a pre-formed gasket in between. Tried endlessly to align and secure it so there would be no leaks when flushed. I had two plummers unsuccessfully try to install for me with no luck. After spending a wad of cash, they said the toilet was defective. LOL I contacted American Standard and they sent me a replacement gasket which didn't work either. I was at my wits end. Then I remembered this product and went out and bought some. I cut a circular piece and incorporated it with the existing gasket, and WahLa! Thank you seller! No recurring problems yet with leakage. I suppose the seal might leak in a few years but I will just replace it. Excellent sealing properties and so easy to install... I recommend this product and give it 5 stars!

Our basketball base had a hole on the bottom. Water would leak out and down would go the basketball court with gusts of wind. but thanks to this product, no more leak

Can’t say enough about the this product. Got a leak in our pool liner after the pool was open (and during quarantine) so our options weren’t many. Boy am I glad I listened to my teenager who had seen an infomercial. It actually sticks in water/underwater. I couldn’t believe it. It’s been a month now and it is holding great. I’d suggest cutting the edges off/making it oblong or a circle to keep the edges from peeling up.

Perfect! Just the right size for the glove box or emergency kit. There if I need it, whether to hold a piece in place in the car or on me!

So far so good.

Used to cover up cracked car trim. Doesnt hold very well so i reinforced it with secondary adhesive. Its thick, durable, matches my car color well. Im in 100 degree weather 4-6 months of yr so its holding up.

I used it on a fuel line for my lawn mower It stopped leaking
