Pricey but worth it
Best sealant. Very easy to install. Well worth the price. Fixed our pool leak.

Best underwater sealant for leaks on a fiberglass pool and the skimmer.
I have a decades old fiberglass pools with multiple leaks. The wall has a hairline crack. Easily plugged with this sealant, even under water. I also had multiple cracks in the skimmer. I had to use my finger to apply chunks of the sealant until all cracks were sealed. Now a year later, those seals are still holding up. This product is much better than all other submarine sealants or cements I have tried on Amazon. It really seals tight and lasts very long. There are two drawbacks. First, it is expensive. Second, it is very thick and very hard to push it out of the tube, even with a caulking gun. Once opened, you are most likely unable to use the remaining that is still in the tube. This is why I am only giving 4-star rating. I am ordering a new tube to work on a new leak and add new layers on old leaks.

Magic is right!
I used this to reattach a drain cover that the screws stripped out. It has been about a month and it's is still holding strong ๐ช

Not exactly up to my need
I checked out several products and read carefully the descriptions. I thought I had a product that could be applied underwater. It said it could be used to patch pool liners while the water was in it. I tried it on our floating dock plastic barrels, but it did not stick at all. I wonder if I could put downward pressure on sealant if it would have worked. I was trying to place it horizontally and couldn't get it to stick. It probably is a good product but just didn't work in my situation.

Sealant cannot be used, too thick.
When I open the item, cut the top then placed it in the applicator, it would not budge much. I placed a screwdriver into the tube and found that the sealant had thickened. I cannot use it.

Works well
Really hard to clean off your hands and makes a huge mess but sure does the job. Unfortunately calking gun wouldnโt fit in skimmer so had to use fingers. I used it to patch up some holes in my skimmer and some cracked wall seams. I used some 2 years ago around my headlight and its still holding strong. The smell is also pretty bad but if it does the job I can plug my nose. Adheres very well but pricy!
