Poor adhesion
Opened can and gave it a stir. Seemed pretty homogenous and didn’t need much stirring but I gave it a few more swirls anyway. Prepped the metal by degreasing with POR-15 cleaner and degreaser. Sanded with 80 grit. Gave it one final wipe with the degreaser and let it dry. Applied the Flex Seal Liquid with a disposable brush. After 24 hours drying time in a 60 degree garage, the flex seal peeled off like a candy wrapper. No adhesion whatsoever.

    I am waiting to see how it works. Using it to seal the cracks between house foundation and sidewalks. Second coat is not sealing holes like I would l like. Too thin? Might need a third coat in some areas. Will know more at end of winter.

    It's a 2 part in which you must mix it all even if you don't need a portion to do the task at hand. The rest is wasted. It should come separated with instructions.
