AUTO BREVITY Ford Rustproofing: The Red River 1969 Continental Mark III being dunked in primer Ford Motor Company called this the Red River STATISTICS: 90 feet long Holds 50,000 gallons 240 volt electrical charge An original Ford Motor Company "better idea", the electrified Red Paint River was a unique way to guard against automotive rust back in the sixties and seventies. Car bodies were placed on a specially-designed hoist and then lowered into a tank containing the liquid. The tank, or "river" was 90 feet long and contained 50,000 gallons of red ionized primer paint, which had a negative charge. But just dunking the car bodies in the primer wasn't good enough for the quality control folks at Ford. So Ford ran 240 volts of electricity through the car bodies, making them positively charged. This caused a reaction between the two components, and fused the negatively charged primer to the positively charged car body. Essentially the paint and the car bodies became one. The outcome was a car that resisted rust much longer than one without this process. AUTO BREVITY is a single-topic, brief look into automotive history from Automotive Mileposts.
