The "wax" that Ford uses is dielectric grease, available at auto parts and electrical jobbers (on the circuit breaker aisle). It is creamy and takes years and years to harden to the state it is in on your '86 F-150.
Yeah, it was hardened. I had to break the bulb and remove the base with needle-nose pliers, then scrape out all of the "wax".
