Yeaah, a guy named Ray tried to give me some magic gel once. It didn't end well and I don't like talking about it.
It does look like a neat gel, but of course could only be used inside an enclosure, and even though it has a low viscosity, it does appear to not turn into a gelatin or solid from what I can see. To me that means while it's nice to take it out, perhaps it would be a nightmare to clean out of stuff it's not supposed to be in? Another wonder if it does flow and how fast in it's cured form.
