J-B Weld...Great stuff for just about anything. Its not pretty but it works.

I've always had good luck with it as long as you rough up your fix area to give it something to get a good bite on. It's either a love it or hate it product. I'm in the 'love it' camp!

I used it to fix my daughter garbage disposal. The seam on the bottom plate cracked and was leaking. Cleaned it and applied J-B and its been leak free for the past 4 months.

Love it!! My dash pad was separating at the windshield. I removed it, used
JB weld and some clamps... Good as new.

Used it for years,cant fault it, I've done everything from casting repairs to fixing leaking fuel tanks on motorcycles, provided surface prep is done right and you follow the recommended ratios you cant go wrong! and the best bit is the repair just keeps getting stronger as time goes on!

I used it many years ago on my '61 aluminum radiator that had a small leak at the top. It is still OK.

I noticed that JB weld now comes in some other forms, including one that you don't have to mix together. I tend to believe that the original product still is the strongest.

My friend used it to save a 502 block. There was a crack at corner of the block that went slightly into the oil filter sealing pad. He used the JB to repair the oil filter sealing area and it worked. No leaks on a block that was on it's way to the scrap yard.

The outer ring of my harmonic balancer walked into my timing chain cover and made a hole in it. I didn't want to take the oil pan off to replace the timing chain cover so I put J-B Weld on the hole and drove it for 10 years before doing the fix the correct way.

I've used it for 25 years to fix cracks and leaks on a variety of things from cars to lawnmowers, "glass bedding" custom rifles and rifle scopes...on and on and on... Really great stuff, short of welding/soldering!

great stuff! I've used J-B weld for years. I brought my 85's door panels back from the dead with this stuff, some .016 aluminum, and 1/8" pop-rivets. J-B works great with secondary bracing and support, especially on plastic interior pieces.





I've repaired, missing and broken tabs on plastic bezels by using J-B with aluminum screening as reinforcing material.

Like Joe and the rest, I have used JB weld to rebuild plastic tabs on interiors as well as many other uses. Alomg with WD40, two of the best products to hit the automotive world!

I like how you sanded it down in the last pic. Little black paint and you wouldn't noticed the difference.

Ive used it a bit

I glued the bottom of the motor on a Suzuki 185 ts dirtbike where the previous owner didn't set the foot brake stop and hit a stump and cracked the motor case. Glued it at 300 miles and was still doing fine at 12,000 miles when the bike gave up the ghost.

I glued the corner of the block in my suburban where the outside starter bolt goes. Broke off around 110,000 miles. Still holding starters at 625,000 miles.

I glued a piston mounting pin socket on a front end loader tractor. Still works fine.

Ive glued about 20 radiators with it I imagine. The metal ones did fine and still are in service. The plastic sided ones didn't take the to the weld so they were a no go.

Ive glued maybe 4 manual transmissions that had cracked cases. All did fine.

Ive glued about 3 automatic transmission cases best I remember. Did fine.

I glued the transmission lines on my bmw when I mangled them changing the power steering pump. No real risk on that one since I was putting a manual trans in it the following month but it never leaked till I did the swap so worked great.

The list goes on and on. Great stuff if used right.

Use a bit of cut stranded fiberglass with it and its even stronger.

Countless repairs with it.

Boat motor cracked block. Someone drilled into the water jacket. I took a PK screw, globbed it with JB Weld, screwed it in there and ran that motor for two more years till I upgraded.

Another boat motor cracked exhaust riser. ground out a vee as if I were welding it, put the JB in there and when it dried, ground it smooth and painted it the stock OMC color. Can't even find the repair now, and it's been at least 10 years.

Just a couple examples...

It just plain works.

I would love to hear more about this process. I've been working different scenarios through my mind and if this worked well I'd love to give it a try. A few details or things of particular concern would be greatly appreciated. Thank you in advance...

For putting two pieces of anything together, clamping pressure is critical. Not too much or you'll squish the glue. Too little and you don't get a good bond.

I installed a new fuel pump in my tank but had to make joints as the wiring was slightly different, I will be removing it this spring and using JB to weld the joints together ( helps me turn that key with out worrying lol)

Anyone know what the shelf life is?

I remember another one. I repaired the fuel line going to the throttle body injection in my old '90 Chevy work truck. Seems there was a chafe... So I wrapped with with aluminum, but before the wrap I JB'ed the repair area. The applied the wrap, with another layer of JB over the cured part. Put tyraps around the whole thing to keep some spiral-wind in place. It's been there several years (I'd forgotten about it).

I did buy a fire extinguisher and mounted it in the truck after doing that. But now it's been there so long, I have no reason to believe it'll be any more vulnerable than the new line I ordered, received, and was too lazy to install.
