Best product for a movie adaptation.
Sweet product in a can, Dwane The Rock Johnson could be able to make a fine movie trilogy about this product starring The Rock, Kevin Hart and an animated bighorn ram named Steve. The plot involves stolen warheads, a salad spinner and the Prime Minister of New Zealand. I don't want to ruin it for you, but worth seeing at least twice in the theater. Perfect help for The Rock to get the EGOT he is truly deserving of. DJ, I have a treatment for you, let me know if you want to talk it over during a business lunch on me.

It works
My bath tab slightly sinks when water is in and no caulking could stand for long time and all cracked. This Flex Seal is the only one which did not crack!!! Just I should have bought past type one. Spray messed up the tiles around but I do not care since it totally stopped the water and happy!

Great product
We live in an older manufactured home. Needless to say the builing materials aren't always the best. Case in point the window sills were made from what appears to be a compressed paper product. Ovrr the years this gets wet again and again which eventually leads to it swelling and falling apart. Do here's what I did. Cleaned the sills with a vacuum and some straight full strength awesome. I took out the high spots cleaned it again then sprayed it with multiple coats of white flex seal. Amazing stuff. This was the 1st time I have used this product. It not only covered the area well but it filled all the cracks in the old paint covered and filled in the divots I made leveling the high spots. It almost looks brand new. The only downside I have found is the fumes. If you decide to try this product please follow the directions specifically when it comes to ventilation.

It worked nicely.
I used this for a cracked shower pan so we could use the shower until we replace it. Seems to be holding up well. I used a cardboard box and tape to treat the area that was cracked. The crack had initially been patched with grey epoxy by the previous owner of the house. It was unsightly but the Flex Seal gave it a nice clean look. You need lots of ventilation when using. The flumes are strong.

Even a woman will be able to use any of the Flex Seal products.
Very easy to use. This product can replace almost anything in your garage you normally use to fill holes, affix things to various products, etc. Thank you for your R&D, Flex Seal. We own most every product Flex Seal makes. It empowers me because I don't have to ask my husband to "fix something."

Si cumple con lo que prometen en la aplicación y cubre bien las partes húmedas.
