Narrative:
On air carrier X, the mechanic assigned to do the walkaround, observed there was old damage on #2 engine C-1 disc, but some of the damage was not addressed and he thought it should be. I inspected the damage and per maintenance manual it did not require removal. To make him happy I dressed the damage to make it look better. I did not believe that I would have to dye pin the blades as the damage could be left alone but it would cause dirt stains drawing your eye to the damage. I dressed the damage and released the aircraft.
