I can vaguely remember from college about how rust forms, differering electrical properties of metals, add moisture etc etc...or something like that anyway. It was a long time age....
But does anyone know the root cause of why its always the rear wheelarches that rust so badly? Is it a water trap, bad sealing, or what?
Don't ships have a dirty great lump of zinc called a 'sacrificial anode' which corrodes first so the rest of the ship doesn't?
In which case, if I weld a chunk of Zinc to my Willy, will it stop my wheelarches from rusting?!!!
No, I didn't think so
