Inquiring minds want to know

For a little while anyway.
My experience is limited to where the previous owner of my boat had used. It is not UV stable, what was exposed turned brittle and crumbled off and even what was covered lost any elasticity. It was applied 7-8 years before I worked with it. The newer stuff might be better.
-
I used it to seal seams in an old travel trailer I bought. It discolors quickly, attracts dirt, and fails if there is any movement in what it was applied to. If you are using it to coat something stable, like a cellar wall, it works for awhile, but ultimately will fail if the temp changes much in the wall.

Ironic considering that they call it FLEX Seal

Come on guys. I've seen it work on TV. I'm surprised they don't build bridges and battleships out of the stuff. [sarcasm off]

I only have limited experience with it. I used it to plug a leak in my ag sprayer's plastic tank. The first time, I used the clear spray-on stuff, and it didn't hold at all. I suspect that my ag chemicals affected it. The second time, I used the white paste (consistency of putty), and it held for the season. I'm not sure about longevity though. I guess I'll see what happens when I fill the tank again this Spring.
I could see where the paste might do well where neither chemicals nor pressure are involved - gutter repairs for example.

Would explain a few things lately if they did. :O

So the stuff is basically expensive caulk (packaging may vary) with extra marketing and advertising which is OK for making some temporary emergency repairs.

Exactly why I asked the question……lmao

It is basically just rubberized caulk in fancy colors. Caulk fails, so does Flex Seal.

I used it he flex tape to temp patch a roof and it works well. Only use I had, still looking for a couple of screen doors to build a boat with.

Demolition Ranch tested Flex Seal for it's bullet proof qualities. Several episodes worth.

I've seen people try to do things to cars with it.
This is why we drink.

A couple of years ago I made a box out of 2x6's to cover the backyard hose bib. Wanting to waterproof it, I painted it with the spray on Flex Seal. The box sits out year round and the FS is still intact.
Don't know that I'd want to use it on anything important* though.
*Like a boat hull or RV roof.

Define "work". As in, what do you need to seal? What material, what context ,AKA a seam, or a thru hull fitting or an expanse of pin holed sheet steel.

Spraying it on the outside of your radiator doesn't work.

Things that do, hot dog buns for a temp fix, the putty type two part for a very permanent one.
