Nothing like a healthy debate!! Once the wife goes to work and removes her car from the garage/workshop I'll make my way through the piles of machinery and get to my bench and find out what sprays and lubes I have. I know I have a can of WD40 white lithium spray I think and a can of dry glide as well. I've used the White speay before on my garage panel lift door and it made a remarkable difference. Between all the pivot pins on the panels themselves, on the rollers and tracks, the drive chain and the spring tensioner got sprayed with this stuff and once it worked in the only noise you can hear now is the motor. Obviously the pressures associated between a garage door and the greenfield clutch will be vastly different though. However I think it's lithium based but won't know for sure till I get to the can.
