Small update..
Booked it in to get painted, dropping it off on the 6th Dec. Deposit paid.
Cleared all the spare parts out of it.
Re hit the surface rust in the spare wheel well with a grinder and sprayed the area with repco rust killer/ primer.
Drained around 5 litres of water out of the rear drivers quarter.
Found some rust under the rear bumper, will be pulling it off today to inspect the extent and repair it if I have time.
Enquired on availability of a heap of parts so should be more updates shortly
