I know a guy who did the job back in the day. It was an entry level job. As you can imagine, spraying paint upward from a pit with a wand like a weed sprayer was a pretty nasty job. So he said that if someone called in sick one of the first guys to leave their post to be a replacement was the core support painter. Depending on how fast the line was running or how hung over the guy was made the difference in what got sprayed. He said he was never checked on by a supervisor so some cars didn't get a very good spray job in his time before he got a job upgrade. If he went to fill in for someone else the other guy in the pit had to add the paint to his job. He said all were supposed to get painted but that is why some cars hardly got any black paint or were skipped.
