Re: Change is possible - it happened with cars
I think it was Porsche was the first to offer a 7 year warranty against rust... either Saab or Volvo were next.
Galvanized metal was used from about 1978.
the main issue with hot dipped galvanized car body panels is that it cant be welded without giving off really toxic zinc oxide levels. I rebuilt a 60's triumph as a kid, using galvanised metal (old volvo bonnets - boxy but good!) in the floor, and the zinc needed to be completely cleaned off areas of heat.
