Thanks- but some clarification please.
' Check that galvanising is OK' - how to determine its not ok? As on the photo, the exposed areas are white powdery metal finish and not rusty, which I thought was the galvanising corroding.
'Rust treatment' -it's not actually rusty, so suppose I can wire brush, cold galvanise paint, and then under seal or clear wax oil on surfaces and cavity wax internally.
