Review: Holds water in my bathtub! Get to delay rehabbing! Yay!! - It works really great! My fiberglass bathtub was not installed properly and cracked… I tried epoxy repair kits and even called out three contractors to quote repairing my tub… All the contractors pricing included replacing the tub and all the tile surrounding it. The cheapest quote was $7000… I bought this stuff, slapped it on the crack after a good cleaning and drying and I have no hesitation taking baths and I’m not getting any leaks in the ceiling below… I’m saving my bath rehab money for the future when I can do a better job! It saved me a lot of money and although it doesn’t look great it’s not visible when you walk in the bathroom as it’s on the interior wall that faces away from the room…
Review: very difficult to pull off if placement is off - covers and conceals like KILZ PRIMER. It adheres like super glue

### ⭐⭐⭐⭐ Great product but don’t believe what you see on tv
*by S***Y on September 2, 2025*

I purchased flex tape for a few different problems I had. The first was a leak in my water storage tank. The other was a crack in a pond. What I liked: ✅ Quality: very strong and sturdy material will definitely hold up over time. ✅ Seal: when used on a completely dry surface and smoothed out creates a water tight seal. Almost impossible to get off. What I didn’t like ❌ not as seen on tv: this product is shown to be able to apply on an active leak and still seal. You won’t get a perfect seal this way and have small leaks. Only apply to fully dry areas. Same goes for clean smooth surfaces. ❌ heat and weight weaken: if this is used where heat builds up and any sort of weight is applied at the same time it will loosen the adhesive. Overall I do like the product to patch things up but don’t use it like you see on tv. Fully clean and dry the area first. If applying to a surface with texture know that water can travel in the small crevices and still leak out.
