Great product
I had a water leak along my truck's windshield. I applied a small bead across my upper windshield, and there was no further water intrusion into the truck cab. It went on smoothly and almost odor-free.

5 stars
This sealant is the best one I’ve bought; I’ve tried several others, but water would eventually get through, and they’d end up peeling off—not this one! It’s easy to use, dries very quickly, and really works! I recommend it.

Great buy. Annoying cleanup in tube
Works great. Helped a lot in my apartment. Only annoying thing is the caulk hardening in the tube and it takes quite a bit of effort to scrape it out. Especially since theres still some unhardened parts inside it that nake it even more annoying

Perfect for small jobs
I didn't realize this existed. No caulk gun needed. I don't recall an odor when. using it. It can be closed and used another time! It has a twist nozzle that allows you to adjust the bead size. Perfect for smaller jobs. It provides a strong waterproof seal. Heavy storms have always forced water into a corner of my kitchen but not since using this. I've painted over it and you wouldn't know its there. Very durable and sets quickly.

Good Product
Was very east to use. Able to redo a bathtub very quickly. Nice repusable tube that is easy to store.

Didn’t stop even small gutter leaks
I bought this specifically to seal a few small leaks in my gutters, but unfortunately it did not work for me at all. I followed the application as carefully as I could and expected a waterproof seal, especially since the leaks were very small, but water was still coming through afterward. I even tried using it on tiny problem areas where I thought it should have been an easy fix, and it still didn’t solve the issue. For a product advertised as waterproof and weatherproof, I expected much better performance. It may work for other applications, but based on my experience with gutter repairs, it was not effective. I ended up having to look for another solution, so this was disappointing and a waste of time for the job I needed it for.
