Did you all know that Galvanized paint was invented back in 1830's, and galvanized metal has been discovered on some armor used in India in the 1700's! So I am assuming it was cost prohibited in the 1970's? Or was the steel used on the 914's galvanized but maybe the technique was not perfected. American cars were built with a predetermined life (planned obsolescence) so the consumer would buy new every several years. Porsche too? (IMG:style_emoticons/default/confused24.gif)
Or maybe they were designed to be bio-degradable, a green product... |

Its a subtle but important distinction, but the chassis cannot be 'hot dipped' post assembly.
I seriously doubt the chassis were 'hot dipped' galvanized post assembly. If so, the seams between separate sheet metal pieces would be filled with zinc, and thats not the case. More importantly the hot dip process involves dipping in molten metal heated to over 800F, and that process easily distorts thin sheet metal. I have seen post-galvanized steel 1/8 in thick in my architectural work be distorted in this process and it is also a very rough surface exactly like a hot dip galvy nail - not acceptable for an automotive surface. Rather, hot-dipped galvanized sheet metal is manufactured in various zinc coating millages where the heat distortion and surfacing smoothness process is managed and can be controlled. |
