Although I couldn't take photos of the casting process, I described it here earlier:

This resin cures in about 4-6 minutes so you have to work pretty fast. The first casting came out pretty good but the bulk of resin had settled too much towards the top and the skin thickness was too thin along the sides. Adding a little more resin to the second casting and concentrating the rotation to the hull sides insured a much more even Lucky #2 cast.
Essentially I rotocasted the mold by turning it 360 degrees - by hand - in all directions as the resin cured to the walls of the mold.
