Love All Flex Seal Products

I tried the caulk and white glue before, and were very happy with how well they work. When I saw the glue in clear, I had to give it a try because white does not always fit the bill -- I don't want white oozing out -- clear is much better! The only thing I would like to see for all Flex Seal caulk and glue products is putting them in containers that can be used until the product is gone. Once opened, it is very difficult to squeeze and get out the product even after following the directions for closing after use. I have to use sticks and whatever else I can find to break the seal deep down to get caulks and glues flowing again after first use. The tube clumps up the product and dries making one unable to just open and squeeze to use.

Bad Product

Product was thick and barely came out of the tube. It was almost unusable.

Adheres very well but ...

The adhesive works very well but difficult to dispense from the tube. In fact it was almost impossible for my wife to squeeze it from the tube. I found it difficult and have big hands and a lot of hand/arm strength. Also don't get it on your hands. It will mostly wash off but leaves a slick residue behind for a while. (Wear gloves) If you can get it out of the tube and keep it off your hands, it works very well. Just make sure it is suitable to your application. I have wrought iron patio chairs and table with plastic sliders on the chair and table feet. Needed to replace them and bought replacements but they kept popping out. Used Flex Seal last year to hold the sliders on and they are still in place. Had more that were not glued on last summer pop off this year so I used Flex Seal again. Same positive results.(see picture)

Worked perfectly and SETS UNDERWATER!

I just want to address some of the comment I read before purchasing this Flex glue, especially the one regarding its tackiness. This glue is not tacky, it isn’t supposed to be. It’s more like an epoxy consistency. It’s made to be used around water and seals and it DOES work underwater. Meaning you can literally apply the glue above water, submerge it in the water and it will set submerged. I glued LED pool lights under the water to my above ground pool (it’s just a small one with a blow up ring) and they have not moved no matter how many times I hit them with the net. I initially thought I may have to drain the pool first, at least to the depth I wanted to set the lights but I decided to try it underwater first since it does say on the tube “sets underwater”. And I sure am glad I did!I didn’t have a problem with the glue not coming out but read some people did. It is rather thick but it absolutely WORKED like a charm!

Its sooooo hard to get it out of the tube

It worked for a piece of glass and on copper. Then I had some magnetic tape that I wanted to secure to the back of an old album. I even weighted it down and left it for the 72 hours, but it wouldn't stick. It is a disappointment. It's also REALY tough to get it out of the tube. Guess I should have just with the spray and the glue I used before I tried this one. For me, nope, wasn't worth it. Hope you have better luck.
