[TR] Off-topic, but car-related

[Mark Hooper]

I've got a friend who spends half his time in Europe and the rest in Montreal.
His car sits in the driveway while he is away. The last time he returned after
4 months away, all the brake rotors on the car had rusted to the pads and he
had to get a mechanic to engage in vigorous hammering of components to free up
the brakes.

Is there some substance out there for spraying on brake discs during storage?
Something that burns off quickly without imperilling life and limb, as using
wax or oil would likely do.
