LOL. My guess is that there are no makes on this because nobody knows where to get the "special silicone" that will work and don't want to buy a dozen brands in hopes of stumbling on the right one. Most silicone isn't going to flow into this well enough to work and from one post it sounds like diluted silicone isn't going to either. Soooooo, yeah.
Edit: I like a good mystery. So, I attempted this mold using a locally sourced RTV silicone. Sounds mysterious doesn't it? Don't worry though, I'll report back my results and even give you a link to the silicone I used as well as the process I tried. Realistically though.....I don't have much hope that its going to turn out well.
