I have used this stuff in the past, with very little luck... Yet if I search on the internet, I can find car threads where folks have used it to fix engine blocks, pistons that have punched through the case, engine mounts... etc... Am I just reading the instructions wrong ? Am I missing my magic wand? Wrong stoichiometric mix? What? Has anyone ever really had luck with this stuff? Anyone really bond metal with it??? And, why has Billy Mays never sold this stuff? Seems like he could glue the space shuttle together with it, and sell a bunch of it!!! Seriously though... anyone use this stuff successfully???
The temperature sending unit hole on my dad's Edelbrock Performer intake manifold cracked and started leaking. He patched the crack with some JB Weld, and it stopped the leak and was invisible. That was 7 years ago and it's still holding up. We put 1100 miles on the car a few weeks ago.
I use the JB Kwik formulation and am happy with its results. I've found it to mend steel to aluminum with no problems. The only thing it seems to fail, and I really didn't expect it to work, was mending a custom tool. Using a spare 10mm socket, I put a glob of JB Weld inside the socket to hold a custom cut-to-length allen wrench piece. JW Weld cannot handle torque, it gave out under a moderately tightened fastener. Patches, fills and mending, it does very well.
Surface prep is the key with JB weld. The rougher and cleaner the parts the petter luck you will have with it.
I've used it succesfully for years. Here's a recent example of a fix on a speedometer angle drive. The key is to prepare the surfaces and know the product's limitations. I used it here to attach a "splint" over the broken pieces. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Don't forget the super glue to save yourself the embarassment of running to the ER for stitches - or am I the only one who has such mishaps? Ummm... just remember to have at least one UNOPENED tube around in case the open one has dried out!
I have rebuilt the mirror stantion on a Gallardo to great affect with JB Weld. Still going to best of my knowledge on a car regularly driven hard and fast.
we've used it at work on tons of occasions for temp repairs while waiting for the machine shop to come and weld something. Not always successful, and certainly not great on something that gets a lot of torque, but a great patch/fix for machine handles and controls. DM
Agree w/ Dave. This is of course an epoxy product, and with any such, correct surface prep is essential; ie, thorough degreasing and ideally, sanding or other roughening of the mating surfaces.
You know they have to clean the superglue back out of the wound right? You don't leave it there......
I purchased new valve guides for our fiat. After hammering out the old ones the new guides went in with finger pressure. Rather than buy the over sized guides,, I heated the head, coated the guides with jb weld and pushed them in. So far so good! Dave P.S. Who wants to go for a ride in my airplane?
I have a fresh set in my tool box for emergency repair on the trail. I have a friend who landed his truck transfer case on a rock which was punctured and drained the gear oil in the middle of nowhere. He JB welded it to get home and replaced the transfer case with a new one later.
I have had great success with it also. As stated above, surface prep is key. On pot metal its a godsend...
I prefer Devcon Plastic Steel myself. It is metal impregnated and is so hard it can be machined like metal. Started using it in bedding rifles but it is great for many things on a car as well.
Last time they superglued my wife's head they told her it would fall off, nothing to worry about. Of course it was on the back of her head, and I guess as her hair grew out, the SG came with it. Now if you superglue ME there, good luck getting the hair to grow at all. Hey, maybe I could superglue ON some hair. DM
Dermaglue AKA super glue just stays on the skin and once healing takes place the glue will start to peal off. Ciao, George
Nice job Tim. I was about to ask how good it was too. I have a leaking oil pan on the Dodge truck, looks more like it rusted out. I can't remove the pan cause the front wheel drivetrain is in the way. I was going to put POR-15 but maybe i should consider JB Weld?
