Great for what I used it for. The only thing I wish that had came with it was something to smooth out the product in the creases around my sink that I filled. I had to use my finger to smooth it out. Other than that, it has worked great for what I used it for. We needed to fill the gaps around the kitchen sink and the bathroom sinks in our house. The color match was perfect for what we needed. It was easy to remove the excess product. It dried fairly quickly too.

Bought this to stabilize a shower shelf. It started falling down. Due to this being clear, I could slather it behind and then caulk around it. Looks good since you can't see the caulk lines & it's holding like it should. As mentioned before, don't get it on your hands, it's hard to get off.

On first use of product, the bottom/end of the tube failed, and calk came gushing out all over. Rigged up a binder clip situation to try to finish project, but even if the product turns out fine, I wouldn't recommend purchase due to failure of the tube itself.

I used this to seal cracks around the window and it worked super well. It was also quite easy to spread with a finger. It has a very good and slightly thicker consistency than most caulking. I will buy again and again!

I have several projects where I need to use waterproof caulk. I chose this brand because it is manufactured by Gorilla, which is an amazing brand. I also wanted to have 2, smaller applicators so that I can have so a break between tasks without worrying about the tube drying up.This Gorilla caulk seals super easy, is waterproof, as well due to its appropriate stickiness. I don't find it messy because of the size of the container and the included tips. Very easy to use, without any mess and it isnt difficult to squeeze out.The only factor that needs to be factored in is that this caulk isn't printable.

Excelente calidad de este producto!, lo utilice para sellar pecera y no me decepciono en lo mas minimo. Incluso con la temporada de lluvias lo utilice para sellar algunas grietas en mi azotea y funciono de maravilla.

For smaller jobs this is so much better than using a caulk gun. Really pleased with this.

It seals! It just depends on your work.I used it during the COVID summer of 2020 to reseal my bathroom shower tub bottom frame, as it had been leaking way too long. This stuff works great! Only this was my first time doing this since I was probably a kid helping my dad. So, my application worked fine, but I still had small leaks even after I was certain I covered everything around the frame! Although the leaks after the resealing were a significant improvement from before!My issue was that I kept going back and retouching the sealant after 10 seconds or so, which would leave bubbled, wrinkled, and overall a less smooth finish than the first time. And, yes… I read the instructions beforehand, but I couldn’t help it! It’s human nature to want to smooth out something that you feel could be smoother, but this stuff dries quickly!! It surprised me. Leave it be and re-do it if you want/need to.Also, a trick I found out during usage is to "over-apply” and smooth out only once as you go. It depends what you’re doing, and how much surface area you need to cover. I learned from this time I hope. That’s what I will try as I bought another of these tubes. The first tube lasted for the entire bottom frame of the standard shower tub door frame. I had a little left to use to try to fix my previous errors, but the small leaks are still there anyway!Gotta try this one again! Maybe with some exam gloves too, because this stuff is messy by the way, and washing your hands with soap and water only does so much if you are doing a lot at once and using your fingers to smooth. Paper towels help with removal of the slightly dried sealant off of one’s hands.
