For most of the amazing props, miniatures, costumes and vehicles that emerge from Weta, the final transformation is done by the talented crew in the Painting and Finishing department. No surprises there - it's all in the name.
Ironically, when you ask them they often claim that the work they do is never finished. And in some ways this is true, as movie props live a hard life and touch-ups and restorations on the fly are part and parcel of their trade.
There isn't a surface or a texture in this universe (or others...) that these guys can't recreate with such authenticity that their colleagues are sometimes hard pushed to spot the replica.
The hard work of the Painting and Finishing department makes the difference between a prop that stands out... and one that truly blends in.
