PART-SPECIFIC BUYING QUESTIONS — original editorial guidance
First decision: Will the tube be visible on every face, and must machined edges match the blue exterior?
Interfaces: Show the tube orientation and the location of holes relative to the assembly. Identify any inserted connectors and surfaces that must remain free of coating.
Finished-part scope: Ask how machining and finishing will be sequenced. A later hole or end cut may expose bare material; state whether that condition is acceptable.
Sample and acceptance: Approve a physical blue finish sample and the agreed hole-check method. A screen image does not set a repeatable color or gloss requirement.
