If someone is a total knucklehead they could use the wrong tool and remove material or damage the part I suppose. Watch the YT videos about the bozos that try to polish their barrels with a sanding disc, etc. But this is safe. I also use Cratex to polish up feed ramps in autos. All you need is some common sense.
