Hi Bill,

I'm pretty sure I used the copper anti-seize compound on my O2 sensor.
I lost two of them in the first two hours of flight because the wire
broke off.  It was unsupported for several inches and I think it was
vibrating.  I don't think the anti-seize will hurt anything as long as
you don't get it on the sensor itself.
