craftgrrl | Labyrinth Movie Jareth Necklace Replica & Question! (Reply)

First off I would like to thank everyone in this community for being my ultimate source of crafting information and feedback - you gals n' guys inspire me to create and give such wonderful and informative feedback! Triple <3's to every one of you!

Ihis was my project for the night and I think it came out decent. The pendant is my attempt at a replica from the movie "The Labyrinth" that Jareth (the Goblin King/David Bowie) wears.

It is fashioned from polymer clay and is not yet painted.

My questions are as follows:

What is the best paint for getting a SHINY metallic finish (like polished silver metal)?
What is the best method for duplicating this pendant?

It took ages to make and reeaaaaallly don't want to make another one from scratch again, but I've never used a mold or anything and don't know anything about them - plus the little spindly "legs" might be hard to duplicate if I don't make the mold right.

Suggestions?

**EDIT** What do I need to use to get an antiqued finish on the medallion piece (center circular element)? Basically it need to be dark in the creases/cracks

**UPDATE** I decided to use silver leaf and it is turning out well!:)

I madeamoldusing Sculpey Mold Maker, but that junk was too gooey so I mixed about 1/8th of the mold maker with 7/8 super sculpey to get a workable texture.

Any recommendations on getting the Sculpey Mold Maker to NOT stick to my project? I tried using flour once and PAM the other time and neither yielded very good results.
