Slip Joint Exhaust Paste?

I’ve never installed an exhaust like this, do you guys use paste at the slip joints? Purpose I assume is to ensure no leaks and that the metal doesn’t rust together? I’ve read the AWE comes with a small amount, but the milltek system does not. I’ve read up the install instructions on the RS7 milltek exhaust which provides a good overview, although no mention of the paste.
