[NONHOG]

Brian, I agree with what you have said, what you didn't know is its not my normal course of action. I was mad at not cleaning the threads first as I know better. Lack of sleep had me on the ragged edge. My wife just had her gallbladder removed and had me getting up early hours getting her pain pills etc.
So add the pressure of my wife's Dad in failing health, who bought the car for my wife. She wants to take him for a drive while he can enjoy it. Then the way overdue paint job on the hood. bla bla bla.
I have read books similar to what you have suggested.
I apologized to my wife and kid and told my boy that was a poor example of how to handle things.
Rather than deal with any attempt at repair last night I walked away. After my meltdown.

Back to the bolt.
I sprayed InForce on it before leaving for work this morning.
Worst case I drill and go oversize (I hope not)
Hoping easy out works. Might see if I can slide a piece of 16G under the threaded area.
Its been decades since I had to use an easy out (been lucky I suppose)
I started this thread wondering if any new tech has developed?
Probably should have left out the tantrum. Ah well.
