2nd Gen Non-Engine/Transmission What primer color is used under PW7 (Bright White)?

It looks like gray, but I'm not sure if that's the primer or zinc coating.

Gray stuff is the primer.

Thanks Charlie, I ended up running out of time so I called the painter to verify and the gray was the right call. He mentioned that they put down a tint before the base coat anyways so primer color didn't really matter (also because the PPG PW7 lays down thick).
