Does Flex Seal really work?

no it doesn't.

Bad experience here. Wouldn't recommend.

Details, please R1 & R2.

No it does NOT work.

I've learned to stay away from the As Seen On TV section at CVS, it has brought me nothing but disappointment.

Yes, the As Seen on TV products universally suck

Are you telling me I can't build my own ocean liner out of chicken wire and flex seal? I was hoping to avoid crowded cruise ships and corona virus infestations by making my own boat, just like the guy in the commercial.

The spray is fine for temporary roof repairs, where you have a leak and need an emergency fix. I'd follow up with a can of Henry with reinforcing fabric tape to do a proper repair for a long term fix.

I tried it in several coats on a leaky faucet coupling, where it worked for a short time only. Ultimately, the water pressure and poor adhesion to the metal caused it to fail.

It worked for me. I used it underneath the kitchen sink on a rental house I own. The rubber gasket was leaking under the strainer body and I used it there over a year ago. I wouldn't normally do such a thing but I was in a bind. I had new tenants moving in and couldn't get a plumber. So far, so good.

Is it paintable?

I guess I should have done a poll.

I’m going to pass for now unless some more positive reviews roll in.

I don't know, R9. I used Flex Shot and wouldn't think it would be paintable. That said, they have a plethora of other products, one of which might be.

Wouldn't using Henry Cavill's ass be kind of impractical?

Any other reviews?

The OP wants to seal in his cream pie loads.

It is crap!

The tape works incredibly well.

I've had nothing but great results with it.

Lol.

I used it as lube and Phil Swift is STILL stuck in my ass!
