I'd like to use something like this:
https://www.amazon.co.uk/Baby-Chromatic-Alginate-Moulding-Powder/dp/B071GPRGDF
To cold cast some body parts with metal powder.

What would be the best resin/epoxy etc to use?

Thanks!

In Essence, you would take a mould from the part you have made then use the mould to cold cast the finished item with a metal powder of your choice.

This video is exactly the kind of process you would do for your project:
