Flex Seal Flex Seal Editorial Review
Flex Paste is a super thick rubberized paste that dries to a strong and flexible rubber coating. It is designed to work on wet or dry surfaces, and can even be used underwater. This product is versatile, making it great for indoor and outdoor projects or repairs. It is easy to use and can be painted any color to match your desired aesthetic. One reviewer mentioned using Flex Paste to repair a leak in a fiberglass/gelcoat shower/tub. They had tried other repair kits in the past, but none of them had provided a lasting solution. After applying Flex Paste, they were leak-free for a couple of weeks and found the repair to be solid. They appreciated that the paste could be spread beyond the crack for a more thorough repair. Another reviewer received the product to try and found it easy to use. They spread the paste with a putty knife and let it dry, and it worked effectively on a small area. They would recommend it to their friends and family. However, there were a couple of negative reviews. One person warned against using Flex Paste in a Koi fish pond, as it left a large oily film on the water's surface that was difficult to remove. Another reviewer was disappointed with the product's performance in sealing a boat. They stated that the paste did not resolve the problem, and it began to shrink and peel apart once dried. They also mentioned that the product was more like a liquid and dripped and oozed during application. Overall, customer experience with Flex Paste seems to be largely positive, with successful repairs and ease of use being common praises. However, there are some drawbacks to Consider, such as potential issues with using the product in water or its Consistency when applying.
