Flex Seal spray works great

I can't say enough good things about Flex Seal products. I swear MacGuyver would be proud of me when I get any of their products in my hands. There's nothing easier to use than the spray just might want to use the paint on if you're using it indoors. The Flex Seal products are 100% waterproof and they perform as advertised. BUY THIS! IT DOES WORK

we had a leak in our gutters on the garage. it faced the back and was hard to find. when i finally found it it was so small that i wanted to try the product. It was easy to use and sealed the problem in one application. easy to use and a great appearance. looked natural .

Love this product. Used it to cover a steel door, with a very ugly poor connection red , which faces East , getting peak sun. It is super easy to use, just remember it does not cover like a normal spray ...it's thicker, since it's a rubber coating. Spray lightly. Take time to see the results, and repeat . I am so happy with my new door, and it covered the red perfectly. Just one of this products many uses. Very pleased, frequent user. 👍
