Flex Seal sucks. It looked like the coolest shit ever. Guess what? NOPE. It’s not anything like what they claim on TV.
For starters, there is nothing about this stuff you can’t get in a sealant in a squeeze tube. That is – unless you WANT a porous wet slime that takes a whole can to seal anything well and even then, probably won’t.
I had a plastic gas tank with a crack in it. I sprayed a coat over it and what happened? Most of it dripped off! Leaving a black stain over the tank. I resprayed and the same shit happened. When I sprayed a lighter coat, it would foam up and I wouldn’t get enough of a seal to cover anything unless I planned to do it 97 times.
Finally, I got the shit to APPEAR sealed. When I mowed my yard, nearly dying from being in such terrible cardio, it sprayed gas out. I was mad so I mowed the whole yard while screaming.
After coming inside to have a couple of heart attacks, I noticed all of the flex seal melted away. Fuck! So I had to reseal the entire thing. But this shit sucks. It’s the consistency of a slime.
I had to get an envelope and basically sculpt/smear the shit into place. Then, I thought “Well, I’ll spray a little on a crack on my city-owned garbage can” just for a little public service. It once again dripped like it was black water and when I finally got a smeared seal over it, it cracked in a day. Yep. The seal was really flexible.
This shit completely blows. I don’t know how they’re not in business yet but take a look at the big nose that sweats to death when shilling this stuff. He’s clearly on cocaine or has some kind of blood pressure problem. We know he’s not worried about a lawsuit, because he’s got about 6 months to live but as for the rest of this company, it needs to be investigated. Shit stuff sucks. Don’t get it.
