No I use a number of primers, I use Ammo of Mig (not to be confused with Mig Productions which AK did the dirty on) One Shot Primer, I use AK Primer & Microfiller, Tamiya Fine Surface primer and Alclad Primer & Microfiller. I can't get on with the early AK Acrylic primers.
It's not my fault you don't know how to use the products............

Never tried German Orange, happy to try anything (as long as it's legal and and doesn't involve same sex, or animals)...........
