69 barracuda question on paint scheme

What (little) I know about this is that they were painted body color and were supposed to be painted black after that. I understand it was done from below the car in a pit and the guy doing it used old fashioned enamel in a pressure sprayer (think bug sprayer or weed sprayer that you punp up by hand). Sometimes it didn't get painted because if there was a person gone and they needed to fill iin on the assembly line guess who left their station! I talked to a guy who claimed he had that nasty job back in the day but soon graduated to one where he didn't get covered in paint by end of shift.
