Getting hydraulic brakes in 1939 cost Ford the rights to his soybean-based
synthetic enamel to quickly get hydraulic brakes once he was finally
convinced they were essential. He traded with another automaker (geez - I
can't remember now... I think Chrysler? - GM stayed with lacquer into the
Ford had developed alkyd enamel - the same material subsequently used by
many automakers for decades thereafter - as part of his huge soybean
research projects. He made various plastic parts of Ford cars from
soy-based plastics as well as his revolutionary synthetic enamel. Alkyd
dried faster and tougher than the previous (mostly) linseed-based enamels.
In fact, alkyd enamel is still used for some industrial painting, and is
still available as house and trim paint outside the Republik of Kalifornia.

1939 was the last year of mechanical brakes by Ford. "FT"
