Wax.

[whiskywill]

I want to polish my cast iron so will call into an Axminster store on the way home from work this evening.
They sell both paste wax and machine wax. Is it worth buying the more expensive machine wax?

I use Liberian lubricating wax and GT85 for all my cast iron work

Lathe, morticer, band saw all get a wipe of GT85 before I close the door, no rust whatsoever.
