One of my chores, once I got the car was to go to a local dairy (up the gravel road) and get milk in wide-mouth gallon jars with wax paper under the lid. It was churned for the butter.
The paint that got eaten off the front valance [of my '57 Beetle] was jet-black Imron enamel, which was new at the time. Same Beetle as in my avatar, after the front clip was replaced.
