I just realized Harry is from NZ. In that case just look for an equivalent moly paste. The Castrol Pyroplex Blue may be available there more easily, bigger company and more market.
EDIT: No longer listed as "Jet Lube" in Mcmaster. I beleive this is it though or an equivalent FYI:
"Extreme Pressure Moly Lubricant, Marine Grade, 1lb Can"
