I was doing work under my truck a year ago and knocked some crud off of the bottom of my cab. There was what appeared to be a small but noticeable spec of green paint. Thought that was very odd and out of place. Nothing on my truck ahs ever been green and every square inch appears to show a factory Yellow paint.
(There are no indications that this truck has ever been restored, just a crappy Earl Sheib repaint in the 80's.)
I soon forgot about it.



Welllllll, when I removed my original steering box a few months ago to put in a big-truck box, the entire area was covered in grease, and look what I found when cleaning the area up:



Is this known to be factory? The black paint was chipping off of the green paint. Both look brand new, must have been covered for a loooong time.

 

Green primer maybe I used green primer in the past on some of the fabrications that I've done.

What if anything is under the green?

 

No its bare steel, which is shown in the last picture. It is odd for sure, especially since nobody else has appeared to report it.

 

Zinc phosphate is a bare steel primer that's green. Kinda like zinc chromate is for aluminum. Not sure if it was being used back then or not.

 

Several things can happen at the plant to cause this:

• At new model startup they sometimes will run a body through the paint shop just to test the equipment. Those bodies are always scrapped these days but who knows what happened in 1956.
• If an assembly plant has an extreme problem with the paint on a body not meeting quality specs then they will repair and and repaint the body . . . usually with the same color but in 1956 maybe not always?
• Special fleet colors are often painted at a facility off line or outside of the plant. If the order came in late they might have taken a body that was already painted another color and used it to fill the fleet order once it was repainted the correct color for the fleet customer.

Does this color(s) appear in any other hidden spot on the body?
