I'm fixing to install my gauges, and after looking at many of ya'lls pictures, I see something ozzing from the thermocouples that looks like never-seize. What is that? I want to make sure if it is something I need, I take that step.

 

More than likely anti-sieze, I used some on mine and there was a little residue.

 

It's anti-sieze and I highly recomend useing it.

 

..........use high temp anti-seize
