The product does not perform as advertised. I used it to seal a plastic trash can lid and within a month it failed and did not retain its integrity

Flex paste has worked great for me but the packaging leaves a lot to be desired. Though it’s “sealed” in a tube, most tubs do not seal out the air. One I purchased had over an 1” of product that was hard as a rock. I think all the tubs should be shrink wrapped, would be worth the extra cost just to get complete product as advertised.

Tried this on my bird bath ,does Not work ,total waste of my money.

Flex seal is the best we did our roof and when our neighbors home burnt our home down guess what the flex seal roof was still standing its very good stuff and you have to coat it a couple times but it works well

A can of the flex seal spray exploded in my laundry room during the night. it was on the wall, dripped down unto my new floor...Covered many of my products I had to throw out. what a nightmare to cleanup! CAUTION!!!!

My Review of flex seal spray and flexseal Can. I own a machine shop machineandtoolservices.com I bought a small cnc mill, but it needed coolant, the coolant tank was leaking in many places, I applied both, can of seal and spray seal, (a must let it sit and cure between layers, i used 3 layers) after a few days i put water in it and tested it for 5 hours, and no leak. My band saw needed a coolant tank too, so i made a wooden box 1/2"thick wood 3ft x 2ft x 4inch wall height, then applied flex seal, both spray and brush on, focusing on the most likely leak areas, with thicker coat, and again no leaks. Do not brush over large gaps and holes, cover first with fibre glass mesh or thin wood then brush on Flex seal. It's a no brainer Flex Seal works, if you do it right. I will be posting some youtube videos of my CNC Mill and Band Saw running flood coolant. Ps, Be patient let it cure and dry for 3days or more, give the rubber a chance to expand into the grooves and small crevices. Any questions just text me Machineandtoolservices web site.

Flex seal tape is totally false advertised. It did not work. I tried to seal a needle size hole from leaking but it did not seal at all. This tape is just like any other tape useless. I contacted company about their guarantee they ignored me
