Factory paint sequence

[TLea]

Trying to get some good idea of how cab with doors was painted. I believe interior was done first. Paint break exterior/interior seems to be at weatherstrip pinchweld for jamb. The door I don't know. I see some pictures that show paint break at rear of door like the door was just closed and painted so just rear edge of door got exterior color and a lot of exterior color overspray in hinge area like you'd expect painting without fender on.
Thanks
