1. A computer-implemented method of coating a workpiece, comprising:
establishing electronic communication between a controller having a processor and at least one robot having a coating applicator;
executing instructions with the processor that control the robot, the instructions written on a non-transient computer-readable medium;
determining, with the controller, a wet-surface time corresponding to each of a plurality of segments of the surface of the workpiece upon which a first layer of coating is to be applied;
selecting at least one segment from the plurality of segments of the workpiece based at least in part on the wet-surface time for the first layer of coating as determined by the controller, wherein the selecting step includes changing a size of the at least one segment to permit complete coating of the at least one segment with the first layer of coating prior to a last wet-surface time of any area in the at least one segment elapsing;
applying the first layer of coating to the at least one segment of said surface of the workpiece with the at least one robot; and,
applying a second layer of coating to the at least one segment for which the wet-surface time has been determined by the controller with the at least one robot prior to the wet-surface time elapsing for the at least one segment.
