2. Question: Is the abrasive blasting process MIL-DTL-53072E just for the inside of the NPC and PC?

2. Answer: The media blasting is to remove the paint from original manufacturing in preparation for the modification welding processes on the NPC. The PC does not need any modification. Therefore, any and all other parts in the assembly, with the exception of the NPC shall be in as OEM manufactured condition or equivalent.

3. Question: Is the intent of the MIL-PRF-24635E Type V class 3 coating for internal NPC and PC only?

3. Answer: The PC does not get modified. The finish call out is for all surfaces of the NPC. If the PC OEM finish has been damaged and is unserviceable, the PC can be finished in the same manner as the NPC, (media blasted to bare metal and refinished).

4. Question: Will the chambers external parts need to be coated as well?

4. Answer: There is no assembly finish call out on the Service and Spring chambers. Each individual part must maintain its finish quality in the final assemblies.

6. Question: Drawing Request: Could you please send copies of drawings 17002C3131 & 17002C1131? The port drawings 17002C3130 & 17002C1130 refer to these as "Make From" parts.

7. Question: Finish: Would either of our standard finishes meet the drawings finish requirement?

6 and 7 Answer: Regarding the finish. The service chamber drawings were revised for the finish to be MIL-PRF-24635E Type V, color 37038. Which is black, two part, exterior (implement) enamel. Essentially, the same automotive paint already used in production. We want the automotive epoxy vendors already use, to make things straight forward.
