This product can automatically flow into the depths of cracks, with high elasticity, crack resistance, frost resistance and sunlight resistance, and strong adhesion.

The construction is simple. After opening the product package, it can be automatically leveled by extruding directly to the crack.

Different from ordinary water-based waterproof coatings, this product can penetrate deep into the root of cracks and completely solve the problem of water leakage.

Saved $60 on a stove oven door handle. I've used this stuff for years. The plastic part where the screws attach to the handle had completely broke off the handle. They had the threaded brass in the center of the plastic. I roughed up the surfaces and used some electrical tape to hold the pieces in place. I mixed the AB and applied it pretty thick. Pretty sure it will last longer than the original.

Renters broke another china made patio chair. Attachment that stretches seat fabric broke, because china-weld uses very little weld. Why not use a little more weld to make better china-weld??? I had to drive screws into metal right by the spot where weld broke (on bothe sides of it) for reinforcement. Then I used 3 layers of JB (took 72 hours to apply). The stuff is liquidy so you just can't apply in 1 go. The chair holds up so far. It will keep on working until some 300lb dumbo drops his drunk derrière onto the chair again :) By basic physics if a butt is flying down it is like twice the weight upon touchdown. So 600lb JB probably won't hold even with support screws. I'll write an update (I Promise!) if and when the repair fails. And why did I use those screws- to have the fabric stretched yet the broken metal piece placed in the exact spot where it was held in place but china-weld. Good repair- and you can't even see it as it is covered by the chair's fabric.

I’ve used jb weld on countless other projects and every time it never disappoints. I had this 70 year old round folding table that I refinished for my grandmothers birthday. I took it all apart so I could sand it down easier and when I took off the legs the middle portion of the table snapped in half completely, I put multiple inch long dabs of jb weld in between the 2 pieces and clamped them together as seen in the picture, after I let it dry and everything was sanded I decided since most of the screws were either broken or missing that I would jb weld the legs to the middle portion. Not only did the middle portion break but each of the 4 feet broke into pieces aswell and the old adhesive didn’t hold them in the wooden dowels. I jb welded them together and back onto the dowels. I was so confident in jb weld that I jumped on the table with all my force and it didn’t budge at all just to show my father that it works wonders. Best adhesive money could buy and it works on virtually anything you need

I even used this to cover the damaged threads of a vintage drill press spindle and then formed the end into a taper with a file. This taper now retains a JT33 chuck that has never failed and has a runout of less than a 64th of an inch. I love this epoxy.

This will really fix your stuff - stuff that superglue can't fix. I've used it around the screw holes on a poor quality replacement OEM dryer handle where they were structuraly weak. I plastered this around each screw hole 'post' and so far no failure after 6 months (whereas another replacement handle cracked after 1 week). I've also used it on a dishwasher soap dispenser where I read online reviews about the closure tab snapping off after a while. So I've reinforced the tab with AB.

I installed an mlok configuration foregrip/stop on a carbine, because I wasn't into paying for and having to deal with a chunky, blocky cage for practically half the price of the firearm. Removed the handguard, chiseled out a slot for the piece, sunk pilot holes, bolts and internal washers/nuts, placed a light coat in and on the underside of the hollow guard over the work I had completed. Came back a day later, hit it with a heavier coat to increase weight for stability, ground down the exterior with a file and sanding block, to the point of ergonomic ideal. This is the stuff you want to use, if your project item does not exceed the heat limitations of the product. You also basically have an unlimited number of attempts if you do not like the effect, as it's as easy as chiseling/sanding off, and it's of better durability than any polymer stock once it sets up. Great stuff, hands down.

Excellent. I used this to fix my 2016 Honda Odyssey keys by following a video somebody posted on YouTube. It worked well, but I did need my dremel tool to get the parts to fit back together perfectly. I can use my keys again and didn't need to get them recut! This stuff saved me and I have some left over for another project. Glad I wrote this review or I would not have thought of this! I know exactly where to use up the rest. Excellent product. Just make sure you squeeze enough out to get a good 50/50 mix or it won't set quite as fast or as you were hoping. I was careful and probably had a puddle, after mixing, only the size of a quarter or a bit larger. Worked great! I recommend

Heard a lot about this product. My Mazda suffered the dash separation problem that has been endemic in hot climates. They even sidestepped recalling this model, but did recall other vehicles. Anyway JB weld to the rescue. Has a high heat rating. Mixed the two tubes 1:1, applied with wooden stick. Put about 100 lbs weight on the dash. No more separation or gap. Curious how long it will hold. Came out great. No more gap adhesive seems to be holding. Make sure you follow directions to include clamp and cure time.

With AB, we were able to repair the frame-- the bond feels very secure. We put the various other pieces back together too (and bent a few back into shape), and now we have a truly lab-grade piece of equipment for our home experiments!

Excellent. AB, I have used for years. These tubes are huge. I undertook several projects using large quantities of glue and the stuff just keeps on coming out of the tube. I think this stuff would almost glue a broken heart.

I've been using this for years in my garage for a multitude of tasks. I had the radiator in my Jeep spring a leak and start to crack. Until I could get a new radiator I patched the area with AB and 2.5 years later I finally installed the new one. It was still holding. It sprung a leak at the drain plug. I always have a package available for repairs and emergencies.

I've been using AB for years, it's the best two-part adhesive out there. It fills and smooths irregular surfaces and joins broken parts like nothing else I've tried. Not brittle like epoxy. Cures non-sticky and machinable. It does take longer to cure, but if you have time it's worth the wait. Un-cured it sags if applied too thick. My most challenging repair was the door handles of my 1969 Alfa Romeo door handles. Most older cars have parts made from chromed pot-metal. This is a brittle metal that can break in use, it doesn't bend and cannot be welded. A portion of my door handle inside the door broke and I couldn't get a replacement. I used AB and had no further trouble.

This stuff was a LIFE SAVER. We were moving from Tallahassee to Charlotte with our U-haul truck. Our truck got double upgraded to a 26 foot truck with a trailer, because they were out of what we had originally requested. We, not being very proficient at driving a vehicle that big, made it all the way to my in-laws house in Atlanta without hitting a thing, except when parking we plowed over my in-laws mailbox. Instead of having to purchase a whole new cast iron mailbox for them, we were able to fix it with this product! Looks great, and saved us some damage money! ***No other mailboxes or vehicles were damaged in the rest of our move***
