Go to your local “automotive parts and supplies store” and pick up a bottle of “oil stabilizer”.

This is weird, high viscosity stuff that retains “slipperiness” under extreme pressure.

It is not unlike the brews used for deep drawing and punching of steel panels etc.

It comes basic, in one litre or so bottles and can be easily decanted into smaller containers for bench work. Costs about twenty Pacific Pesos (Oz Dollars) per litre, here, as opposed to the scary prices for the “proper stuff”.

It IS NOT water soluble, so the same care and handling / processing procedures apply as do those for anybody else’s non-water-based lube.

Works well on surplus brass that has been spat through machine-guns, etc.

AND, it works in the engine of your car.

Bonus points: get the Lyman Tungsten-carbide decapper kit with the Lyman / RCBS optional die-plug parts. The TC expander ball effectively eliminates “neck-drag” and its associated squeal. It also removes the need to inside lube the brass with anything; Purists may use graphite or Moly powder to really slick things up.
