Prepare the surface and apply surface protection coating and examine the coated surface on the part by one of the following procedures. Refer to Figure, Figure and figure 3. Unless otherwise stated in the figures, apply coat all over the part.
SUBTASK 72-41-21-380-156 Apply Surface Protection
Use temporary marking by SPM TASK 70-09-01-400-501.
CoMat 06-073 INK, METAL MARKING must be completely dry prior to application of CoMat 07-125 LACQUER.
Apply two thin coats of CoMat 07-125 LACQUER to avoid dissolving ink pigment. Allow each layer to dry prior to the next coat.
Heavier application of CoMat 07-125 LACQUER is permitted after the light application of the coating completely dries.
For PN 6A3500, PN 6A4310, PN 6A4569 and PN 6A7019, refer to Figure, Index [4].
For PN 6A6548, PN 6A7529, PN 6A7578 and PN 6A7624, refer to Figure, Index [2].
