Why cars rust

I been a car person ever since I could remember and growing up in New York is no different from almost anywhere.

I honestly believe that neglect has more to do with rusting then the weather or the way any of the states take care of their roads when there's snow as I have had my 64 Signet which was bought in New York and for the first 20 something years of its life, it lived in NY, however it was garaged and well taken care of, washed, waxed, interior cleaned, underside washed and rust free. Ive owned around 12 Porsche's which were bought between NY, NJ and PA and all were at least 20 years old and rust free. There are not many persons who would take care of their car and baby it, body and interior the way real car people do, so in reality the majority of car buyers actually let it go and are not really car people, you know them and we've all met them. Even collectors play games with knowledge they believe they have as some only have respect for the green and not for the automobile.

While living in Canada during the late 70's and driving an old Ford custom pickup, my girl friends father told me to have the underside of the truck sprayed with oil for the winter so the salted roads wouldn't rust the chassis, he was into strange stuff and experimental air planes and gliders.

I'll wager you that there are many ways we can take care of all aspects of the car in order for it not to rust either when new or again after the metal is restored. Just like the secrets of race engines, there's probably a hundred things we all should know in regards to this but whether or not, some will take the easy way out and sleep on it.
