JB weld, flex seal or full rebuild ?

To my knowledge there is 1 guy that grinds for a few different companies/brands and he always grinds them a little off, be it cause the specs were **** and wouldn't last or who knows. Engle does their own, but I think bullet uses him , the one guy, too.
I knew his name once upon a time...
I have gotten cams suspect on the phone and when the cam showed up the card was not exactly what was spoken about on the phone. Sometimes what we want and what's actually going to work are 2 completely different things.

It was one of their off the shelf grinds.
