I'm in enough trouble already with my opinions on other things, but Im sorry, there is no way glue has any place whatsoever in vehicle restoration. Just the variable temperatures (expansion and contraction) alone would preclude even the thought. You even have to be careful what alloy metal you use when welding to ensure you are not introducing stress issues into the mix. Wow!
I have been known to grab the JB Weld every now and then for adding extra strength to threads, etc, but over the years I have seen way too much glue and plastic fail way before it should have. Best to take all of that enthusiasm and learn how to weld properly. Weld through Primer is what you were looking for.
