Originally tried it to unglue some assault marines legs from their torso's, (Want the legs for some berserk charging blood claws). It didn't work, however, it did clean them more.
The pieces that I placed in simple green had been cleaned up via metho but there were little patches of paint in crevices that wouldn't budge, till now. These-models-are-spot-less!
So! Still looking for something to separate heavily glued models, but discovered a great cleaner... Be well!
