Turbo rebuild businesses love you!!
There's is nothing wrong with rebuilding at home. A scratch will not destroy them. If that was the case, nicked wheels would explode easily. I've been around a lot of turbos with severely nicked blades that were fine. Big drag racers don't even use ait filters because nothing can handle the airflow without restriction and inject dirt like a vacuum cleaner.
As said, scribe a tiny index line and torque back to spec.
