I don’t think that’s going to buff out:
Sacrificial part. The place I was CP at had a documented history of prop strikes on metal vs composite and the after effects from follow up inspections. The metal props generally resulted in metal in oil within the 35 hour "monitoring window" and would lead to gearbox replacement. The composite props had zero gearbox replacements during the same stretch, though the blades would obviously explode when they hit something. I can't remember the numbers anymore, but the prop was way cheaper than the gearbox.Wow, those composite props just disintegrate.
