[AT] Rust magic?

[David Bruce]

The most useful "rust buster" I've tried is PB Blaster but I have come 
nowhere near trying all options - I'm sure better options exist.
As an idea - only an idea because I haven't used this treatment to free 
moving parts - but I have used it before to remove some surface rust 
with good success.
Try a citric or phosphoric acid solution as a soak.  Either will 
dissolve surface rust and just maybe remove enough rust to allow you to 
regain the proper movement in the track sections.
