If you are happy with it leave it be. Someone else can always get it done if they want too.
For me a small chip or scratch polished out is not an issue if it is done well and not noticeable. I would clean a dirty oil painting. Other people probably think my opinion is heresy.
Selling an item is a bit different though as
any damage is going to affect value, as long as buyers know then they can act accordingly.
