Platsil Gel-10. Harder than it looks.

Our first attempt at working with silicone quickly descended into hastily slopping it around just to see what it would set like and all we really learned was that without thickener there is not a lot you can do except make a mess. So, after picking up a bottle of Thi-Vex Silicone Thickener from 4D Model Shop we set about trying again.

The second attempt is definitely a step up from the first but it is safe to say that it is not as easy as Brick In The Yard make it look and that many hours of practice are going to be needed.
That said, Gel-10 is great stuff. It is much nicer to work with than the latex and tissue paper we have used in the past and while it is more expensive I think it is definitely worth the money.
The main thing to learn is going to be how thick to make it for different applications and how it behaves at different stages in it's curing process so you know when to stop shaping it and just let it set.
There is also a shopping list evolving with each session. Currently it is only some more pigment colours and a set of Skin Illustrator alcohol activated makeup (which is by no means a cheap list for a next to nothing budget) but there are plenty of other things on the horizon that will become 'essential' to us soon as we get in to more specific applications and maybe start to do some moulding work as well.
