Flex Seal MAX The Flex Seal MAX is a waterproof rubber spray-on sealant coating that claims to stop leaks instantly. It comes in a 17 oz, 2-pack, and is perfect for use on gutters, wood, RVs, campers, and roofs. Based on customer reviews, the experience and reception of this product seem to be mixed. Some customers had positive experiences with the Flex Seal MAX. One customer mentioned that it effectively sealed the inside of their gutters, preventing any leaks. Another customer found it useful for temporarily fixing a leaking bulkhead, using the Flex tape to cover the rotting wood and then sealing it with the spray. They described it as a great tool to keep water from coming in until they could get the bulkhead fixed. However, there were also a number of negative reviews. One customer mentioned that the substance was very runny, resembling spray paint, and it did not seal the cracks in their boat, even though they followed the instructions. Another customer found that the product rubbed off quickly when they tried to layer it on their steel toe boots, suggesting that it might not be suitable for certain types of equipment. Additionally, one customer experienced a nozzle breakage issue, causing it to spray everywhere during the second use. In conclusion, the Flex Seal MAX has received mixed feedback from customers. While it seems to work well for some specific applications, such as gutter sealing and temporary fixes, it may not be as effective for other uses. Customers should be aware of the potential for runniness and nozzle breakage.
