I'm sorry for kept you waiting^^
I'm really excited to hear, that you used my tutorial for your own Witchblade!
Now to the tricky part of the latex:
The latex-milk that I used is from a hobby-shop, especially for designing of relief moulds. It's white, runny and a little stinky in his liquid form.
I covered my plaster-arm with a paintbrush. (For the Blade I don't think that I need a really smooth surface) One layer, drying, next layer, drying...with a hair-dryer you can reduce waiting time. After three layers I let it completly drying. I hang the glove up for this. That cost me some days, then I started to brush it again with Latex-milk (that's the point where you can see, on which parts of the glove the latex is too thin) This game I repeated once again. That's the chapter that needed the most time. I needed for this more than a week.
When you let the Latex really dry, it isn't gluey. So you can peel it slowly from the plaster. At the wrist I had a little problems and killed my plaster-arm, because the plaster broke.
And the tipp from Larethiana is truly helpful, if you mixed for the last layers acrylic-colors with Latex. The color is nice and more flexible.
I hope I could help you! And good luck for your next steps!
