Those are my first casts of 3 finished parts.  I used polyurethane Axson F16 resin. Very quick de-moulding time (2.5m pot life, de-mould 20 – 30 minutes).  It has low viscosity so  it flows like water to all details.  Silicone mould rubber T20. Its hard to get those materials here in Dublin so I ordered it at http://www.tiranti.co.uk.  It arrived quickly and well packed. The bad surprise was delivery cost over 20£ for 4 kg parcel.  You can also buy resin from this Ebay seller, I checked him and he is reliable.
