Claim 14:
15. A method of seal coating a first surface, the method comprising:
loading at least a first seal coating material into at least a first mobile additive manufacturing apparatus, wherein the first mobile manufacturing apparatus comprises:
a navigation system to determine location,
a controller capable of executing algorithms and providing control signals,
a vision system capable of scanning a first surface and measuring a topography of the surface as the first mobile additive manufacturing apparatus moves over the first surface,
a drive system to move the first mobile additive manufacturing apparatus,
a first mobile additive manufacturing system to deposit at least the first material for seal coating in a prescribed location on the surface according to a digital model processed by the controller,
a power system capable of providing power to operate at least the drive system, navigation system, controller and the first mobile additive manufacturing system,
a chassis, wherein the chassis supports all of the navigation system, the controller, the vision system, the drive system, the first mobile additive manufacturing system and the power system, and
a rotary dispensing system, wherein the rotary dispensing system comprises a rotary gantry, wherein the rotary gantry is moved by a motor driving an element around a central axis supported by the chassis;

moving the first mobile additive manufacturing apparatus with the drive system, wherein the amount of movement is controlled by the digital model; and
dispensing the seal coating material on the first surface while the first mobile additive manufacturing apparatus is moving, wherein the amount of the seal coating material dispensed is controlled by the digital model; and
wherein the rotary gantry comprises at least a first squeegee and at least a first nozzle, wherein the rotary gantry continuously rotates around the central axis while the nozzle dispenses the first seal coating material, and wherein the rotating squeegee spreads out the first seal coating material on the first surface as the first mobile additive manufacturing apparatus moves across the first surface.
