Yes, the interior of the doors get the interior color, and I took the exterior color to the same point as the line you put on the picture. But I have to point out, does it really matter? What I mean is, that entire area will be covered by the black sponge rubber door gasket, so there is no way of really telling how an original truck was painted. So I figured exterior color should go around the door edge and disappear under the gasket, and interior color start some place under the gasket.
As for the seat frame, I did mine in interior color, and believe that is correct.
