    I thought the subject was why my bus didn't rust? & what it was made of?
    Maybe if the battery 'vomits'! Why? Since the battery is isolated from the body;)
    I was just looking at the anodic argument..& saving the bus from rust;).
    Cheers

    Proof that batteries do vomit.

    Mr Google is your friend.
    https://en.m.wikipedia.org/wiki/Rust

    Actualy the mild steel is a purer form and closer to elemental iron.
    Rust is a compound molecule.

    Which has nothing to do with decoding for Petra nor why my bus didn't rust:).
    Back to the anodic scale we go;). A reminder cbus;) http://forums.kombiclub.com/threads/76-sopru-resto.54261/page-11
    Your quote:

    "Wouldnt tout myself as having any more than a basic knowledge of metallurgy.";)

    Aluminium tray reduces electron activity from the battery area due to the anodic argument. Not the vomit from the battery as I've seen that lots. As 1500king says "keep the electricals tidy".

    You have a non rusty one primarily because it has not been exposed to conditions that create rust.
    That is the major factor.
    If you were lucky, it may also have been rustproof.
    Something I used to do at a car dealership and as a panelbeater have compared results years later on crashed cars.
    It is quite effective.

    And washing the crap that holds moisture in cavities, not exposing it to chlorine,salt,detergents etc that contain salt, all helps.
    All kombis can be considered to be likely to have hidden heavy surface rust ,at least , in cavities so it is advantageous to, at least once, blow a heap of lanolin thru those cavities and along all seams.
    That is 50 years of experience. No degree necessary.
    Just adherence to scientific principles of observation , hypothesis, test hypothesis, consistant repeatable results, conclusion.
    Something ,at which, I am adequately adept .

    Back on topic fellas.......
    Want to argue the merits of metallurgy ?
    Start a separate thread.
    Cheers,
