To date, people have used heat and/or chemical methods to successfully remove black epoxy from D2E chip. Just curious, have any modders/hobbiest tried using expansion/contraction differentials? Since this is a "suggestion" category, I suggest someone with extra boards to play with exhibiting the dreaded black substance try a "freezing" method of removal. By this I mean, using liquid nitrogen or even dry ice. Wouldn't it be great if careful application of a cryrogenic liquid made the epoxy brittle and it just "pop" came off in one chunk..so clean you could apply a snap on clip!
