I would disposition this as:
"No defect, cosmetic in nature only. Does not affect form, fit, function or reliability of unit. Color bands are not needed after assembly, and test results prove all components are correct. Reference Designators are present on PWB for future component identification if needed."

Subject: [TN] Color Bands of Resistor Get Washed Off
We are putting together an assembly that must meet IPC-A-610 Rev F inspection reqts for Clss III.
After SMT THOLE resistors, where the marking could be easily seen, were hand soldered in to place. The entire assembly was washed and then inspected. At this point it was noted that the bands were pretty much no longer there.
The boards were tested and then conformally coated and shipped. The client noted the defect of the missing resistor bands.
What would the call be?
Thanks
