No - Another bomb

Getting a lot of rain and having gutters one would think problem solved. Gutters leak, so this seemed to be the answer. It didn’t even slow the water down. Save your money and time and do even consider this.

No - Flex Seal Scam

This stuff is a cheap automotive undercoating. You would be better off going to Pep Boys, Auto-zone, etc to the real stuff. 3M makes a rubberized undercoating that is far superior.

I sprayed TWO CANS of this stuff inside and outside the basin of a small birdbath that had a drip leak. It still leaks. Don’t waste your money.

This stuff would not seal a cracked plastic tea pitcher mush less a screen door bottomed boat. What a joke. It did make a nice bbq pit touch up paint.

I was upsold six cans of Flex Seal and it doesn’t work. I tried it on the underside deck of my pontoon boat to seal a crack and it absolutely didn’t work. After using one can and taking the boat out it still leaked. I used another can and no luck. Stay away from this one!

No - Two coats...still had a leak.
2 stars2 stars2 stars2 stars2 stars

I had a leak in my roof under the cooler. Sprayed the area with 1 coat, waited 24 hours and hit it with another coat. Still leaked with the next rain. Hit the area with 2 more coats over 24 hours and the leak stopped. It did get me through the rainy season, but it’s certainly not the product “advertised!!” The big glob of black was ugly, visible and I think would have melted into a tar river and run down the roof on one of our 105 degree summer days.

No - First try, it did not work

I had a gutter corner that was leaking. I scraped off the old grout and gave the corner joint a good cleaning before I applied the Flex Seal. It was the middle of summer and we did not have rain for several weeks. When it did finally rain, the corner joint leaked like a sieve. Now I have two cans of this useless product.
