This worked great! I am repurchasing due to some of it drying but that can be due to my son not closing it properly. It filled in some gaps and cracks at my front door perfectly so now I will paint it to see how that goes. You can't see where I put it at a casual glance so that's great.

I have door threshold that has been leaking for as long as I can remember allowing water into my garage. I replaced the threshold and found this product to be the easiest to apply. It will take more than can if you buy this size. The product is outstanding to use, easy to use. I am sold on using it any where I need to.

Difficult area to caulk. This product is thick and allowed me to get it to stick using finger application. My only concern is that half the cans had a thin film on too on top where it started to dry. I chipped it off and used the rest of the can. This is also reason for buying several smaller cans so they would be used and I would not have opened can storage. Otherwise great product.

Just like they advertise, It does the job. Easy to use. Easy to clean.

Used this to patch a leaky fiberglass fountain on our patio. It had several big cracks and this stuff did the job! Its super thick and gooey, but wasn't too hard to apply with a spatula and it adhered well. I personally applied it when the fountain was dry, but it does say you can apply to wet items. It's been able to hold up and stay water resistant while submerged in in water. The size looks small, but it's enough for a couple small jobs or one big one. I used almost all of it to patch the fountain.

It's not working! It's like a scam; very small leaks didn't stop it!

It does not work well with water. It says it will even work under water so I tried to use it on a barely leaking swimming pool pipe. It just drips right through. It does not work under water or mine is bad because it did nothing on a pipe with a minor drip. Also, once exposed to air the contents in the can solidify. It’s a one time use product. Edit: the product didn’t work for me but the company did reach out and refund the purchase.

I needed to seal in around an outdoor light fixture and wanted to give this a try. I have gotten tired of the caulk tubes and you know what I mean when you always have lots left over and by the time you need it again it's bad. Like that you can use a utensil for applying it and you can close it back up. Function like a putty. It's water resistant and it sticks. This is stronger than traditional silicone.
