"Rare Options - 1969 Chevrolet Liquid Tire Chain ($23.20)
Just 278 Chevelle, 188 Camaro, and 2,086 Impala and Caprice vehicles were equipped with the Liquid Tire Chain option from the factory in 1969.
A button inside the car near the steering column dispensed the aerosol chemical onto the top of the rear tires. Two dispenser assemblies were mounted in the luggage compartment by Fisher Body and held the canisters. A cap with vacuum hose attachment sealed the compartment. Manifold vacuum activated the spray when the button was depressed. Dow Chemical developed the "traction improver" solution.
Seems like a great idea, especially for cars destined for snowy or icy areas of the country. We hear that it worked better on ice than on snow"
