From experience. Phospheric acid will not turn clean steel black. It does turn the rust to a nice black though. And 2 phosphate will not come off easy, like a paint will.
And I can agree that not each and every TF truck was created the same. Nor were the BC trucks. There is constant bragosus in the GMC literature about the efforts to spray rust inhibitor in doors and cowling plenum. We all know if these things were painting correctly in the inner areas of panels, there would be no rusty cabs and sheet metal. I still stand by the frames painted black at conception, maybe not everything added to them was painted though. I do know for a fact there are 4 1/2 ton trucks that were painted from the factory. A 57, 58, and 2 59's.
Oh and a 59 GMC too.
Oh as far as a 55, they were is such a hurry to get them out the door, that it could be likely they cut all sorts of corners to do that. And not waiting for frame paint to dry could be a good place to cut a corner. The TF 55's are kind of a bird of a different color so to say, even the numbering is not typical TF.
It is obvious by the continuation of the Advance design trucks into the 55 model year that, they were behind in the TF departments, I wonder how close it came to not having a 55 TF truck?
The cameo.
The inside bed walls have been painted black, must be part of 2 tone cameo stuff. The frame shows the yes cheap paint, they didn't prime them, just what ever the paint was, likely fast dry lacqure. They evidently played with it
and removed the white paint stick marks on the firewall. Things to notice: the interior paint is not shiney, its a dulled paint. Hmmm so even cameos had stock interior colors then. The body color deal must have been an option? Wonder why the wood looks like its been wet?
