Tried to find some info on the Falcon Heavy grey paint. For those that don’t know, apparently it was an adjustment made to the falcon heavy upper stages, to increase the heating on the RP1 tank, to try to prevent freezing during long coast phases.

There's a little more to the Mission Extension Kit, via https://en.wikipedia.org/wiki/Falcon_9_Block_5#Improvements

dark-painted band (for thermal control), extra COPVs for pressurization control, and additional TEA-TEB ignition fluid.
