Pliable casting resin?

Posted in Custom Workstation

I'm customizing some MOTUC Horde symbols, but I'm running into a bit of trouble.

I've made a mold out of DAS clay, now I need to make a cast of it, but I need something which will still be pliable after it has cured in order for me to shape it around the figures body, not completely soft, just enough to shape round a body and glue on.

But I have no clue as what to use. I've read about using epoxy resin, but doesn't that cure to a solid state?

would household silicone work? Because even if it didn't just take the shape of the mold (I.e. it spilled over the sides), I'd just be able to cut off the bits I didn't need.

ANY help would be most appreciated.

Thanks
