        3. NOTE

          CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER is a non-chromated alternative to CoMat 07-035 CORROSION RESISTANT COATING and CoMat 07-104 ALUMINIUM HIGH HEAT RESISTANT PAINT.

        1. For PN 6A3651, PN 6A4101, PN 6A4161, PN 6A5992, PN 6A5995, PN 6A7623 and PN 6A7626, refer to Figure.

        2. For PN 6A6540, PN 6A7577 and PN 6B1430, refer to Figure.

    3. SUBTASK 72-41-21-350-277 Mark the Part

      1. Mark the part with the part number and VRS6161 adjacent to the assembly part number.

      1. Use temporary marking by SPM TASK 70-09-01-400-501.

        1. CoMat 06-073 INK, METAL MARKING must be completely dry prior to application of CoMat 07-125 LACQUER.

        2. Apply two thin coats of CoMat 07-125 LACQUER to avoid dissolving ink pigment. Allow each layer to dry prior to the next coat.

        3. Heavier application of CoMat 07-125 LACQUER is permitted after the light application of the coating completely dries.

      3. For PN 6A3651, PN 6A4101, PN 6A4161, PN 6A5992, PN 6A5995, PN 6A7623 and PN 6A7626, refer to Figure.
