Did I search on the word and didn't come back with any result.
In any case. I came across this material while trying to cast a pair of of range finders from my E-75 for my Tiger II mod build (10.5 KwK).
Anyway onto the material. These little block thingy comes from Japan. I first saw them in Japan couple months ago and was wondering what they were and I came across them at the local hobby shop again couple of weeks ago.
You soften these block up by warming them up in 80C water. Once soften you press your original into them to get the impression. No mold release agent is needed. I cool it in cool water afterward - not sure if that is needed. I pop the original out and cast the parts using polyester putty. I was very happy with the resulting cast - even the weld seams and the mold line (lol) from the original showed up
The best thing is these are suppose to be reusable - just warm them up in hot water again.....

To be honest i've never used it, but i've read on modeller reviews that is very useful for modelling scratchworks
