I had a shop foreman on a different forum a while back comment that he had an employee repeatedly twisting off grade 8 lugs because he was using anti-seize and putting the full torque to them. He took the anti-seize away from the guy and solved the problem.
He should have taken the impact gun away from him, as it's obvoius that he didn't know how to use it. That's what I do when I get rookies that overtorque wheels, make 'em put 'em on BY HAND for a few days. That usually fixes the overtorqueing issues.
We use the torque sticks in the shop I work for, most fo the guys use the shop provided sticks, not sure of the brand, I have my own set from Accu-Torq. I've used them both dry and lubed, seems to not make much difference in accuracy. However, I've been doing it long enough to have a feel for the tool and what it's doing.
