Ships are big bits of iron floating in nice corrosive salt water. Ship owners put a big bit of zink on the outside of the hull, it corrodes away before the ship does, so why don't we have these for cars?

       This idea is fully baked... Lots of modern cars already use Hot zinc plated steel for panels etc

       galvanised? (or galvaniZed for our american cousins)   

       as far as I am aware, EVERY car made with steel goes through a galvanisation process...

       Auto bodies go through a zinc chromate primer bath early in the manufacturing process. In addition, many corrosion-prone areas are made from galvanized panels. This caused a number of recalls in the '70s, and '80s, as the paint used at the time adhered poorly to the zinc.   

       All metal car parts should be powdercoated, anyway.
