An apparatus for coating a work piece includes a process chamber, a coating material supply apparatus located at least partially within the process chamber for delivering a coating material to the work piece, a pre-heater assembly adjoining the process chamber, and a support for holding the work piece. The pre-heater assembly includes a housing that opens to the process chamber, a thermal hood positioned within the housing and configured to reflect thermal energy for reflecting thermal energy toward the work piece. The support is movable to selectively move the work piece between a first position within the housing of the pre-heater assembly and a second position within the process chamber and outside the housing of the pre-heater assembly.
