Is Flex Glue better than JB Weld, Gorilla & Loctite? Let's find out!

  • Published on: 24 December 2018
  • Flex Glue competes against JB Weld, Loctite, and Gorilla glue using wood, brick, PVC, and metal. Flex Glue and JB Weld are also used to glue an engine together. Will either product provide enough strength to allow the engine to run? Let's find out! I purchased all the products tested and I'm not sponsored by Flex, JB Weld, Loctite, Gorilla, or any other company or manufacturer. I do the best I can to provide unbiased and accurate testing.

    Will flex seal in an engine crank case stop oil leaks? LOL

    Is glue vs epoxy an apples to apples test?

    I would love to see JB Weld vs PC-7 vs maybe a Loctite epoxy. I am a big fan of PC-7 epoxy.

    You should do a video on the extreme limitations of JB weld and see just how nice of a product it is? Also, any idea of toxicity after its cured?

    In the snap test from metal, you should hang something from the bolt straight up and down instead of sideways. Also, you should measure roughly how much of each glue you're using. Would be nice to see how economic they are, and also to be sure your not applying more product to one test subject, and not the other. Noticed in the wood test the glue coverage was not equal.

    Add water to gorilla glue or it will suck! My step dad said he threw a bottle away because it sucked. I asked if he added water to it and he looked at me like I was purple with pokie dots.lol. ADD WATER TO GORILLA GLUE OR IT WON'T WORK

    For an exhaust leak on the vehicle, furnace cement works a lot better than JB Weld. JB Weld burns at 300, furnace cement burns at 2100. Feather it over the hole in your exhaust, let it sit a hour then drive until it's warm, leak is fixed

    Got an idea for you, testing ‘emergency leak repair tape’ on a pressurised cooling system or even a pvc setup with pressurised air and water in it. Probably done it already 😉

    So, Gorilla and Loctite is sold as what exactly? Gorilla and Loctite is no more than a BETA item to get the customer's money according to this video.

    I really enjoy watching your test videos. I hope you can keep doing them for a long time. Your tests have saved me money several time over.

    not really a fair test / no great surprise as JB Weld is two component and the other three Products are not. if the matching Products (aka 2C) from the other Companies were used this test would be much more valid.

    For wood it should have been loctite construction adhesive and Gorilla wood glue.

    Do you think JB Weld would be suitable to hold a chainsaw decompressor on a shallow hole bored on a motorcycle cilinder head?Thanks

    Gorilla is sold everywhere and is heavily promoted with POP shelf space. I have never bought it ever.Thanks to this test I won't have to waste my time.

    Jb weld works well for permanently gluing in spark plugs on a disposable bucket truck... 7 years later n it’s still running the farm

    I always had great results with the loctite and you have confirmed my experience with product in many more ways than I ever have. Great work!

    I was waiting for you to stand on the stack of weights there for a minute! JB Weld is crazy strong! Maybe they should make denture bond! HA!

    I liked these tests, though the wrench drop test seems a little less scientific as you had two variables that were somewhat arbitrary... the drop height and the weight of the wrench change, so I don't know which is more of a contributing factor.Super great testing though!

    Can you do a video that test an underwater situation? Maybe some different epoxy to concrete and if it can set up and hold while wet . Thanks
