Maybe not the best comparison, two part epoxy vs. flexible but interesting non the less. Great back story on JB Weld https://www.jbweld.com/pages/about HOW IT ALL BEGAN: A MOM AND POP OPERATION The J-B Weld Company was founded in 1969 by Sam and Mary Bonham. Sam had discovered a need for a “cold weld” product to use in his truck service garage, instead of traditional torch welding. Working with a Texas A&M chemist, he formulated an original “tougher than steel” two-part epoxy and named it J-B Weld. Sam and Mary soon went from selling the product out of their car to auto parts jobbers across Texas, to selling it in stores throughout the U.S. and internationally.
Haven't watched the video yet, but I can tell you from first hand experience this past week that if you have Gorilla tape on the holes in your jeans side pockets, TSA will take a serious look at you in the Phoenix airport. The guy wasn't impressed when I told him it held up to multiple washings, either. That was about the time he was rubbing his hands all over my pants, and not in a way I cared for.
Always had good luck with jb-weld Once worked in a shop where the customer really pissed off the mechanic for some reason. Mechanic was doing a diff service on a full size Chevy pick up and job-welded the cover on after the service !! Gave him shit for that as your not pissing anyone off except th next guy working on the diff and real easy for the owner to pin it back on us. Reall Asshole thing to do. But after watching this video probably better off to scrap the diff then even try and pull the cover off.
The guy that did this video has a whole series on You-Tube testing lots of things like seafoam, Marvel Mystery Oil, pouring water through the carb to blow out carbon deposits, and so one. He's no scientist but he does a god job destroying lawn mowers for our entertainment and education.
Oddly enjoyed watching that. I must be easily entertained. Thanks, blowby. Tell me, guys. Does JB Weld hold up to high heat? Would you, for instance, use it to patch an exhaust manifold?
https://www.jbweld.com/products/highheat-epoxy-putty Looks like Epoxies fail below the iron, steel, red zone.
JB stopped coolant leak from headgasket at front edge of block on customer's car , he didn't want to replace gasket .
Thanks for the link, pitman. Ok, so even though the "high heat" JB is recommended for exhaust manifolds, anything above 400* is questionable.
Any contact is better than none? Testing a two part epoxy against flexible glues seems a bit odd to me , if I get the urge to stick a bolt to a piece of metal I’ll get the mig out.
Honestly I have never had any luck with the quick fix stuff so I just toss the part or break out the welder.
