What is the likely corrosion here?

70 Charger. Recent purchase. Plug wire ends and distribution cap shows quite a bit of some colored residue.
Planning on replacing plugs, wires, distributor.
But curious if there are any broader implications elsewhere based on cause?

Dielectric grease???

Does that harden over time? About 5-6 yrs old.

Kind of looks like white lithium grease
