A method and apparatus for recirculating a waterbased paint in an vehicle painting assembly line includes paint totes (41) located substantially adjacent a circulating tank (55) near the point of application of the paint, thus reducing line length and the cost of replacing the paint in the line. This feature is enabled because waterbased paints, unlike solvent-based paints, are not subject to the same volume location restrictions. By maintaining a supply of paint to a low volume tank within narrow limits, a high volume application requirement can be met. A single line recirculating system is also disclosed for use with either type of paint. A number of features of a working paint system are also disclosed, including orbital welding of the stainless steel tubing, passivation of the line, use of DI water for passivation and flushing of the system, low point drains for the system, limited surge, and the use of smooth bore components and transitions to avoid paint sedimentation and buildup.
