Whats the worse repair that you have ever made with JB Weld (That failed)?

You can also name similar products success of failure stories.

 

i got a "hot" faucett **** on my homeade pipes that was rattling apart, pulled it off and JB'ed the baby and she has been solid as a rock to this day

best failed..... i was trying to make a jockey shift outta an old WWWII pinnaple grenade and didn't have a die big enough so i figured if i just jammed a **** load of JB in there and then jammed it on the shifter rod i would be good to go......not so much lol

 

Best: Boat hull (I hate boats that sink!)

Worst: Haven't had a JB failure...........

 

Best: A broken flange on a tunnel ram intake for a small-block Chevy.

 

Best : Broken tab that holds the oil pump inside the transfer case on my 89 Bronco. It's held up for 7 years now with no problems.

Worst: I cant think of any failures either.

 

The oil pressure sensor on a 2000 Ford Ranger. Held for over a 100K and was still holding when my OL totaled it.

 

BEST-- Sealed an external crack in a Chevy block, as far as I know it is still holding today.

WORST-- I attempted to repair a cracked exhaust manifold on an old ford truck. I guess it was too much heat there.

 

Plastic fuel tank on a dirt bike in the middle of Baja. Held for years until sold. Never had a bad one. Took the emblem off my backrest and JB'd two small bolts to it and bolted it to my backrest bag. Still holding after two years.

 

Seen a guy put some on a72 nova ware the block split from freeze lasted for years.

 

Awesome stuff! Fixed a Christmas tree stand and a rear view mirror on my truck...holding strong ever since!
