Yes, I meant to add "keep the metal guard, whatever you might wrap it with".
I think epoxy is too permanent, you might want to replace the guard with a differently shaped one, or remove it so a potential future buyer could see the chainstay is not damaged. I might try hot melt glue as a sticky but peelable option. Otherwise there are some very grabby double-sided adhesive tapes. Or use many small clear zip ties with the pawls tucked out of sight.
