Anti-seize compound on lugnuts?
My understanding is that torque is based on the friction between the lugnut head and mating surface as opposed to the threads themselves. If this is the case and I put Permatex on the threads but keep the tip dry, the torque reading should be negligible (~5-8% off, which may be nothing, given the variability in calibration on most torque wrenches). 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???

That's trueBut to be fair, i've been doing it on my G35 since i got the car in '07. No issues at all. I don't use a ton though.
But i understand where this comes from. Bolt torque does use friction as a factor and using a lube changes the torque value. Same concept as lubing head bolts. This kinda gets into it a bit
