Color codes (Current)

[scoutingranch]

I see on the Kaiser Willys Auto Supply catalog the color pages with numbers. But, that tells me nothing without more intel on those numbers such as who the manufacturer is so that the paint company can cross reference.
Do I have my facts right? Or, am I blowing smoke as usual?

I want to order Potomac Gray in rattle cans. Yes, rattle cans. There is a supplier I use that will make the paint and they have a neat spray nozzle that is wide vertical. I will be doing the entire vehicle. They also sell tractor paint in many colors.
Thanks lads
