Coated Metal Inspection: Keep Removable Smears Separate from Permanent Marks
A visible mark may be removable residue or a change in the finish. The distinction determines the next step.
Updated · NANOLAB Knowledge
Practical approach
Use the approved gentle cleaning method and reinspect under the same light before proposing restoration.
A handling smear that clears after cleaning should not be reported as the same defect as a persistent scratch.
Decision limits
Do not escalate immediately to abrasive repair or conceal the original observation with another protective layer.
