Fluted slides repairable?

[Arrowhead]

I have an Olds Recording that has a nick on the inner slide- just enough to cause a bit of scraping a noise as I play, to the point where it's bugging me and I don't want to play it. is something like this repairable?

Sure is fixable! Take it to your tech. If you don't have one try John Sandhagen, Eric Swanson, or any number of tech that are on this site.
