Flex Seal?

Has anyone used Flex Seal? It's been advertised on TV to stop leaks in windows, roof tops, pipes & a host of other things. They have a funny sales video that shows how the sealed a pickup truck & made it into a submarine.

Yes.... I have used the liquid and the tape.
They are a little on the pricey side but they do work.

Nothing but a band aid for something needing a real fix!

And yes I tried it once and proved that it was krap!

Rustolium sells a competitive product. We sell a lot of it and I have had no negative feedback. Most people use it on gutters.

Interesting that is exactly what I used it for, did clean up, etc, still leaked.

Now I had a bigger mess to fix, got it cleaned up, used proper gutter sealers, leak is gone!

People love the quick fix but seldom does it really work as intended.

I used it [might have been an off brand] on the insulated fiber board return air box for my heat pump. It worked well for that but I'd be leery using anything like that as fix for leaks. When it does work I'd expect it to be just a temporary fix
