I heard back from Co-Motion today & I believe they are in Hueyhoolihas's camp. They state: "The rust inside is superficial and actually adds a protective layer, despite that sounding counterintuitive." I don't know enough about metals to have a valid opinion, but it seems to me $5,000 frames should be protected against the possibility of rust in some way. That said, I knew it was not and am sorry I didn't use Frame Saver when new.
Thanks for all the comments.
