Our trucks are BIG. They take a lot of paint...My Fire Truck required 4 gallons. We started spraying and it was looking great. Then on the last coat I opened the last gallon of paint...started spraying over the rear wheels toward the back and discovered the paint had been mixed wrong(it was several shades darker)I was not a happy person. The paint store gave me another 2 gallons to paint from the cab back but I lost all that time and work.
I could have avoided that problem by pouring all 4 gallons into one container, stiring it up and mixing out of that container.
I hope this story saves someone else from a similar experience.
