I just watched the latest clips, I am learning new things from this already.
I forgot the open hand had that raised lip around the wrist area, you explained what you need to do to get around the problems of air bubbles gathering in that area. I had no idea it would make for extra work looking forward to seeing how this is dealt with. The alcohol was also something i knew nothing about and the extra work with clean up you do during this phase of the process.
It's interesting the way you have keyed the silicone, no chance of unwanted movement especially the Rotocast parts, it looks very robust.
I am really enjoying the vids, totally kick ass idea
, your a Pro my friend.
