How long does Flex Seal last?

I'm curious about the longevity of Flex Seal. Can you provide me with some insight into how long it typically lasts? Is it a temporary fix or does it offer a more permanent solution? I'm looking for a reliable sealant for my project and want to ensure that it can withstand the test of time. Additionally, are there any factors that could potentially affect its lifespan, such as weather conditions or the type of surface it's being applied to?
