DAve Hi,
and damage is even more extended and serious when you start "playing" with sea water or sand. Lots of Landies here in Greece have been subjected to this tornment and eventhough our road are very seldom covered with salt during winter you can find several cars suffering from rust beyond repair to both their bodyshell and mechanics due to salt water.
Actually one of my main headaches is washing the camels with fresh water following a windy day (my house is less than 5 meter away from the sea and seasalt spray is constantly covering them.
Take care Pantelis
