Correct..Servisol is the way to go. But if the track is worn or
damaged then replacement is the only long term solution.

But someone must have manufactured the track in the first place, so it
should not be beyond the bounds of possibility for us to attempt such.

Well it's going to very difficult to find and if you do it'll be very
expensive to buy an OEM part.
