Great stuff

Works great. Completely stopped rain from leaking through my overhead lights on my Freightliner Cascadia

Do NOT order more cans than you will need for a project- as these are not eligible for returns

Ordered two cans to complete a project (sealing the bottom and sides of a water feature in backyard). Product works very well, but I only needed to use one can to complete the project. Unfortunately the second can was not eligible for return. 😒

Works well, stores terrible

Used to coat Texas-Sun exposed top edge of an Intex pool. Application went well and, so far, so good. Be prepared to throw away your brush and, please know, the product in the can will not stay a liquid, even with a can top perfectly installed and...sealed with flex seal. Buy only what you need

Beats expectations

This is first time with this particular Flex formula. The results are amazing as it leaves a flexible rubber coating. I have an older favorite cracked sprinkler..water sprayed everywhere except where it should. This product filled in all those plastic cracks and it now works like new. Did not have to toss and help fill up landfill. Dogs have 10 year old 6ft rigid plastic pool..also ready for dump. Was able to fill all cracks and they are out playing in it.Edit: I Realize I used this product for minor repairs just to practice and try out, but have no doubt all the experienced DIY users commenting on their great experiences using for bigger repairs are correct.

Dented Can

I'm guessing the product will work just fine, but not impressed with being sent a dented can.

Coated my workbench for electronics repair work

I coated my whole workbench in my garage with the stuff and they turned out amazing. It was about 45 degrees, so I put a little space heater on it and it dried in a couple hours.

works better than expect as put on with a brush

Works great and seems of good quality and can be layered to the thickness you want. As dries quick so buy extra brushes or rollers.Update 7-25 I needed this stuff to think out as using more like a paint where if you use it otherwise it kind of runs. Mineral spirits from rust oleum is what I used to thin it. Manufacture says you can't but you can and it still dries like normal as I first tested in a jar and solidified like a hard rubber surface.Just so you know nothing sticks to this stuff as paint and other type of rubber coatings unless it is of the same chemistry as why I had to thin this stuff out and use with a fine brush but dries fast like starts in minutes and then really unusable in about 15-20 minutes for the same effect.
