Is this correct?

This is based on the compound used, with slicker compounds (low friction) making the torque even more pronounced (excessive by 20-30%) thus warping the rotor and stretching the threads. Permatex is not a low friction compound, so this is less of an issue. Wouldn't this change the torque specs in just a small amount but considerably reduce the break-loose-force once the connection has sat for a while?

BTW-- your 127lbs exceeds my full body weight by >15lbs.

And what's with the unprotected sex???

You are correct to a point. There is more surface area in the threads than the clamping area of the lug nut to the wheel, so both play a part. I started out, long ago, greasing or using "neverseeze" on my studs, but after I had a few back off, I have never done it since. I work in the Oil and Gas Control Valve Industry, and I have seen more busted threads in piping because of using neverseeze on pipe threads than anything else. You do have to compensate for torque values when using it.
