Ok, that's what I thought you might have been talking about. Like I said in my replies over there, great photos and they do document that the interior was the first to get painted. But the first picture that mothertrucker posted still leaves the question open as to how they masked the interior when they shot the outside.
From what I have seen and heard the cabs were painted with red oxide primer. I thought they may have even been dipped at one time but I've never seen any evidence of primer on the cabs interior so that kills that idea.
There is a little splash of red oxide primer inside outer skins of the door, I assume that was for rust prevention where the rain ran down past the side windows. Now the original exterior Mariner Blue paint on mine has red oxide primer under its entire exterior skin on the cab. The hood and front clip has black E-coat under the Mariner Blue.
I just went out and crawled under the passenger side of the cab and took some pictures. It will take me a couple of hours to get them downloaded, edited and posted to my album, but I'll get them in there tonight sometime.
There is undercoating on the cab underside outside the frame rails. I cleared off a section of the undercoating on the right rocker panel and there is red oxide primer under it. This tells me that the red oxide primer was shot at least on the outer sections of the cab floor bottom. Outside the frame rails it was undercoated over the primer. Down the center of the cab floor bottom there is no evidence of any paint, primer or undercoating at all and it appears to have been delivered with the center of the floor in left bare metal.
