I've tried to smooth out as much as possible. Still trying to get my head around the sculpting. I use Milliput. Sticks and hardens no need to oven bake. Very durable as you can see from the transformation of Galvy.

Bumblebee was a touch up from a bad design before using clay mold.

Cleaned it up at the front a little, still got some residual but a good paint test.
