IMHO...
buy yourself another, get one as close to the one you have now as you can get then strip the rustor for parts for the new one and take what you can get for leftovers.
and in answer to the poms question about the outback dust rusting vehicles...
yes, well sort of...
its ok while its dry but what happens when it gets wet is the moisture gets through the dust then dries out, the top dries first and makes an insulation type layer to help keep the moisture in. This rusts the metal beneath out it mainly applies to steel body work and non galved or well painted chassis say anything not landrover :)
