Have used JB Weld for decades... Amazing stuff.

Friend of mine is a drag racer and Super Stock Champion on multiple occasions at Beaver Springs. He once had a cracked block and JB Welded it together. Made multiple winning runs for a couple more years before he sold the engine to someone else.

That said, while the video is informative, I doubt any one of these products is intended for every possible application, with each of them suitable for their own applications.
I might Flex Glue or Flex Seal a screen door to the bottom of a boat But I wouldn't use any of these on a cylinder head that may someday need taken apart. That's what gaskets are for.

I have to admit I've never purchased any JB weld, but I sure will now....what an interesting test.

I use PC7 a lot. I wish he had included it in his tests.
I watch a lot of his videos. Not very scientific, but interesting.
