How did Nissan paint a Patrol?

I am sure we might have some different opinions on this subject but here is what I have learned over the years.
First it is obvious if you have seen a Patrol in original paint or fairly untouched that all the hardware on the truck was painted with the body. Everything from tire carrier to windshield latches to seat mounts were all painted on the body. If you have ever taken a Patrol apart it becomes even more obvious. Under all this hardware is primer, usually red oxide primer. So obviously, individual parts were painted in primer and the all bolted on the truck and painted. This goes for the entire body minus hard top or soft top and perhaps windshield frame and doors. It was a mystery for many years for me, did they dip these things? How did they do it?
Patrols were not dipped. They were sprayed on an assembly line. They were assembled as far as tub, floor pans, firewall, front inner and out fenders and the rad support. Hardware was put on like door hinges. It would have had to been done on a "jig" to support the body. They went down the assembly line on this jig and got sprayed. After this the mostly complete body would have been lowered down onto a completed and built chassis. Picture if you can an overhead assembly line in terms of how things are moved around. Meaning rail road type tracks on the ceiling that the bodies are hung from on the jig and moved around the plant. I know they were painted with front fenders on and even the rad support on because the gaskets between these body panels on an untouched Patrol has paint on it.
There is simply no other way to paint the truck with all the body hardware painted and even paint on the body gaskets.
On top of this Nissan plated, mostly zinc, nearly every bit of hardware on the truck before assembly and painting. I know this from sand blasting it all, under many years of paint you will find the zinc coating before you get to raw steel. Now this was very smart of Nissan because as paint chips on wear items like the tire carrier or the door latches raw steel is not left behind under the paint. This stopped any bleeding of rust when paint chipped. Hood latch stuff is another great example. Some items they did leave in plain zinc such as the seat sliders or the springs inside the windshield vents or the rods/levers for the kick vents or the hood support rod or the throttle linkage.
The grey interior paint is an oddity if looking at 60 series Patrols on a world wide scale. Only N. America received it from everything I have seen. Very strange they would do this extra step in the paint process for just N. American Patrols but if somebody has a picture of a non-North American Patrol with grey interior paint I would love to see it! I personally really like the grey interior paint on N. American hardtops. I think it makes the trucks look that much better and makes N. American Patrols a bit special.
Another interesting thing is Nissan seam sealed these trucks. Depending on the year depends on how much seam sealer. Early trucks, say 62-64 didn't see a lot of sealer. But by 66 they were getting seam sealer where the floor pans mate to the seat frame as well as the firewall and the seat frame to the tub. In addition depending on year even the trans hump was seam sealed down. All those bolts to hold down the trans hump, they got painted with the rest of the truck, the exception being the small access panel that is part of the two piece trans hump covers. While these days we may say, man these trucks get rusty! Back in the 1960's Nissan was ahead of the game by doing the seam sealer. You won't find it on a Jeep of similar vintage that is for sure.
What say you!?
