A system is provided for automatically measuring paint film thickness of painted bodies for closed loop control of a paint process for painting the bodies in a paint booth. The system includes a cell for receiving painted bodies from the paint booth and a conveyor control system for controlling the movement of painted bodies between the paint booth and the cell. The system also includes an AutoPelt system communicating with the conveyor control system for measuring paint film thickness of the painted bodies in the cells. The system includes an integrated paint quality control (IPQC) monitoring system communicating with the AutoPelt system for receiving data of paint film thickness information and combining the paint film thickness information with automation parameters on a vehicle identification number (VIN) basis of the painted bodies to control paint automation equipment of the paint booth.
