No Zimmerit,
The last Panthers to fight in Berlin in May that had come directly from MAN in mid-late April 45,had no zimmerit as it was discontinued 7 Sept.1944 by order of Generalinspekteur der Panzertruppen. I think the chassis number for the one I am building was Fr128568, it was painted in primer (RAL: 8017) and green (RAL:6003)*.
It was equipped with the newest IR that was around, it also had those armor plates that were over the intake/crew heater compartment/exhaust and all steel road-wheels.
*Stocks of Dunkelgelb (RAL:7028) were depleted by this stage in the war.
