Anybody know of a "super lubricant" ?

I have metal on metal contact between moving parts that should not
have contact.

I have been using WD-40 so far to keep these parts lubricated enough
to allow motion between these to meatl parts, but I am sure there are
other, more technologically engineered friction reducing compounds
available to some application.

I must exclude greases, and limit it to thin, high viscosity spray
applications.

Thanks
