About Flex Seal Spray Rubber Sealant Coating
74% appreciated its fast drying time
I drained the tank and wet vaccd the standing water out then let it dry out for a few days before applying the sealant. This highlights the significance of drying the surface before applying the sealant.
76% appreciated its moisture resistance
I applied the hardware-sealer to the screen door of the boat and it held up to the water pressure, indicating its good moisture resistance.
