Pretty Good Stuff
I got the white color. It sprays on like thick spray paint and takes a while to dry. It won't stop a pressure leak unless it's used in conjunction with tape but I think I might use it to seal the old tile walls above my bathtub. It's easy to work with and a can goes a long way.

Barely thicker than paint - leaves pinprick size holes that still leak after repeated spraying
I had one simple problem - seal the bottom of a plastic window box planter so that it didn't leak water. Spray, dry, test - leaks through pinprick holes. Respray... still leaks - respray... still leaks. REPEAT CYCLE 6+ times over three days - STILL LEAKS! Threw the rest of the can out and went to Home Depot and bought Rust-oleum LeakSeal - that worked the first coat! The paint pro at Home Depot agreed that the FlexSeal product was junk and that many users had complained about it, but that the Rust-oleum version worked much better!

Mastic rubber sealant spray, good alkali chemical resistance
I needed some sealant for an alkali oxygen-hydrogen (separate stream) electrolysis device. Such devices are typically operated with around 10-30% potassium hydroxide by weight in solution, which means that everything inside the cells is exposed to an extremely strong alkali solution for months or years on end. Mastic rubber is one of a relatively limited number of sealants capable of enduring such harsh conditions. I applied 4 successive thick coats of Flex Seal White Spray to the internal joints of the PVC electrolysis cells after I initially hot glued them into place (also decent for strong alkali but needed further sealing to prevent gas leakage), waiting at least 12 hours between applications. The result was a highly uniform and tightly adhering continuous layer of mastic rubber, reasonably thick and bright white, matching the rest of the cell components. I did not observe any indication of leakage, peeling, cracking, or any other form of failure. Industrial references indicate that mastic rubber materials tested survived continual exposure to 50% or higher slurries of potassium hydroxide indefinitely, exceeding my requirements. Hopefully it will continue to hold up well in ongoing use. I do not anticipate any issue given observations and research to date.Read full review
