I’d have thought doors being manufactured today, even for some old vehicles, would use new steel products.

why are you being antagonistic?
if you don't think you are , read your posts again.
everyone here has their own right to post what they like.
thats why we have a great team of moderators , of which you are not part of.

jog on, champ.

You've owned 30 land rovers and NOT ONE of them has had rust in the doors? My dude, I can guarantee you this is not true. Boggles my mind why people insist on behaving like this on this website. If you have nothing to offer the person asking the question then you absolutely do not need to post. Get a hobby.

Make that 2 50 plus year owners that haven't experienced defender door rust, not in Vic residing vehicles anyway. I did buy a '85 county ex Qld that had it on one side - including the door pillar, but it was a coastal one.
Land Rovers that have never been in coastal climates, or gone for a seawater swim, or drive on salted roads don't door rust. Simple. Its just you've never experienced it,

yes, galvanic corrosion only exists near the sea because the laws of physics are different there. Good job on owning defenders for 50yrs, I didn't realise they were available in 1973.

Cmon guys. It’s Friday, relax a bit

You learn something every day...

It is actually chemistry, not physics, if you want to nitpick, and whether galvanic corrosion occurs depends primarily on the presence of water and the presence of electrolytes as well as the care taken to insulate the metals from each other. Since 1948 Rover and their successors relied primarily on paint to provide the insulation between the two metals.

This is not particularly successful, but it has to be noted that as they also relied on paint to protect the steel used in the construction of the vehicle, and that some of this, most notably the bulkhead and chassis, are almost always more badly affected by corrosion than the alloy parts. And this is not galvanic corrosion, although it can be argued that the worse corrosion experienced with Series 3 vehicles is because of the quality of steel used (which would be galvanic in a sense reflecting slightly different potentials from neighbouring domains with different alloying ingredients), I suspect that quality of paint and painting as well as preparation have more to do with it.

Regardless of this, it needs to be born in mind that the vast majority of Australia is arid, so any Landrovers* used exclusively inland, which probably describes most of them, bearing in mind that the mass sales were as working vehicles, they spent most of their lives dry. At the other extreme, those used on the coast, and especially driven on beaches, have not only been wet most of their life, but often have added from the sea water electrolytes that expedite corrosion.


*I am using the term to refer to Landrovers from 1948 to 1989, but only their descendants, Defenders, since then to 2016.

Landrovers were initially a specific model built by the Rover Car company, which merged with Leyland in 1967. This merger was so "successful" that by 1989, the successor company, looking for a name for the marque, after both Leyland and and Rover had been turned into dirty words by mismanagement, turned to "Landrover" as the only model name that had not been blighted and applied it as a marque, to support the new Discovery model. This meant a new name was needed for the Landrover model, and "Defender" was selected.

and here we have are facts, not just opinions blurted out and presented as facts to criticise others opinions.... but facts, thanks John.
