Somewhat off topic. During the early '60's Chevrolet experimented with Delrin as a durable weight saver on the engine cooling fan for the aircooled Corvair. Problem was that battery acid destroyed the plastic, which gave off a type of toxic formaldehyde gas. Not a very safe idea considering the engines hot air supplied the cars interior heat.
