As part of my ongoing Star Trek Online Starfleet uniform project, I'm making a set of combadges and ranks pips via cold casting with Smooth-On products.
The badges and pips are golden brass for the 2409 version and silvery aluminium for the 2410 version. Due to their small size, shape and the use of two-piece silicone molds, I'm thinking of doing a solid resin/metal fill rather than just a gel coat, but I'll definitely dust my molds in metal powder first to further improve the lustre.
In order to get the desired bright* golden brass and silvery aluminium effect:
- What ratio of resin part A : part B : metal powder should I use? 1:1:1, 1:1:2, 1:1:3 or more?
- Is it necessary to tint the resin? If so, what color?
- If the tint is black, would it be better get Smooth-Cast Onyx (which is already black) or Smooth-Cast 325 with the appropriate colorant?
Advice, suggestions and accompanying photos would be greatly appreciated.
*I may weather these badges later on with black shoe polish
