Oil axle prep vs graphite

Is there a big difference over how you polish or just what you apply after you polish?

For me I polish graphite to 3k grit and oil to 12k grit. I also spray graphite axles with sailkote (most use pledge) and oil axles get max pro or jig (jig is the faster). Make sure you polish and wax wheel bores for either lube.
 
Is this what everyone is referring to when they say jig?
