A lot of waterborne paints (basecoat) is of a polyurethane make up. I know PPG for sure and possibly Sikkens are made up of latex resins. The PPG waterborne base is fully suspended... basically you don't even need to "shake" or "stir" it as it doesn't settle. All of the mettalics are suspended. No mixing banks are needed, you basically pull the toner off the bank and tip it back and forth 3-4 times and pour. All of the pearls are liquid now too.
