### ⭐⭐⭐⭐⭐ Awesome Product
*by A***R on April 10, 2026*

Great product. Did the job and didn't need a caulk gun

### ⭐⭐⭐⭐ Good seal
*by C***. on August 12, 2024*

I re-caulked my bathtub with this. It took a bit to get the caulk “flowing” but was pretty easy to use after that. I gave it four stars because it seemed a bit sticky to work with compared to my old caulk gun caulk—but it does seem very water resistant. I would get this again—just need more experience w it!
