Works great

It works and it's durable when dry. Used it on rusting pool rail. Coated well and stopped rust. Used in the bowl of decorative fountain. Stopped leaks. Useable again. Wish it wasn't so expensive. Great stuff.

Flex Seal

I purchased this to seal the perimeter of my backyard shed. So far so good however I am waiting on a heavy rain, to see the results.
