What could be the story

All the colors were in pressure pots in a paint room . You would just grab the hose for the color that was grease penciled on the firewall and hook up. The guns were electrostatic . The paint would wrap around corners on its own. The paint room guy Walt was incharge of keeping the pots full of the colors and marking the hoses. There were two sets of hoses on each side and pairs of painters would do every other truck at the same time. Then they would go up hill into the oven.
That's good to know. How many different colors did you paint?
