Both of the names that you mention, Liquid Metal ", and " Tech-Steel, sound familiar. I am sure it was one of them, more probably Tech-Steel. I did use it for both, Radiator repair, (High pressure), as well as Catalytic converter repair (Very High Temperature). It held permanently in both cases.

I also used it for various other repairs around the car, many vibration sensitive areas. Never failed yet. I have no doubt that the Oxygen Sensor can be repaired with this epoxy very easily and permanently
