1. A multi-component coating dispensing system, comprising:
a first pump in fluid communication with a first reservoir containing a first coating component, the first pump configured for propelling at a first specified drive rate the first coating component received at an inlet of the first pump,
a second pump in fluid communication with a second reservoir containing a second coating component, the second pump configured for propelling at a second specified drive rate the second coating component received at an inlet of the second pump,
a controller configured for determining the first specified drive rate and the second specified drive rate based at least in part on providing from the first pump and the second pump a desired ratio of the first coating component to the second coating component, and
a usage tracker configured for providing to the controller actual usage data for the first coating component and the second coating component, wherein the controller is configured for comparing the actual usage data to a corresponding calculated usage for the first coating component and the second coating component, and
the controller is configured to determine an adjusted drive rate for at least one of the first pump and the second pump for providing the desired ratio of the first coating component to the second coating component based at least in part on comparing the actual usage data to the corresponding calculated usage for the first coating component and the second coating component.
