Miliput is a different animal if your used to the ol' GS, best thing to lubricate your tools with is alcohol, and no I don't mean your local micro brew!!!
Plain rubbing stuff, the rules for it are the same as GS mix, attach and rough shape, wait 20 mins or so and do your detail.
I use it mostly to bulk up an armature before GS, I have started to mix it with the GS, that way it has a bit of elasticity from the GS and is a bit softer to rough work.
