The fleet colors are batched up for sure, I don't see why they'd have to do that for the normal colors.
I assumed the paint, reducer and hardener were all mixed through the system, not premixed.It IS a big deal because the paint is mixed in 40 gallon drums in the paint room. Can't let paint sit in the vats weeks at a time without being used. That is the reason Fleet colors are done in blocks.
Thanks. Learn something new every day...There is no hardener, this is oven bake. The paint is mixed in the paint room in vats then lined to the booths so every gun and robot in the booth is spraying the SAME color from the SAME mix. It would be a nightmare if every gun and robot in the booth was spraying from a different mix.
