The short answer
Photograph and describe newly discovered damage and agree it before continuing work outside the confirmed scope.
Why the first inspection may not be enough
Bumpers, covers and other components can hide mounts, structure and mechanical parts. Safe dismantling may be needed to assess them.
Create a clear record
Take readable photographs, name the elements and note when the damage was found so it can be compared with the earlier record.
Do not start extra work without agreement
Confirm who approves the change and how the additional scope will be documented before continuing the repair.
