How automakers fought off the scourge of rust — Petersen Automotive Museum

To recap: yes, early autos had been even now prone to rust, but they were being thickly developed to the position that most had been despatched on their way in favor of one thing new ahead of their authentic house owners started off to observe any key problems.

That all started to change in the early 1970s. Automakers ended up gradually switching above to unibody-form design as nicely as additional ornate and elaborate vehicle layouts in almost each and every segment of the current market.
