The only time the JB weld let go on my muffler was in a very bad crash. [8D]
I've tried it on various things.
It works like a champ on anything that doesn't build up a lot of heat...
But sooner or later ( and usually sooner ) when I use it on mufflers it turns it a grey chewy mess, that doesn't brighten my teeth!
