I tried to repair a header flange on an old Alfa of mine with JB weld.
It sure looked pretty until I actually tried to use the car and the JB
weld incinerated in clouds of smoke.
It's not for extremely high temp applications.  Although there may be
some newer products that are high temp.

                                                                                Mike Garske
