I have an electronic device that uses black potting materiel similar the one below to I believe to protect the electronic components from elements.
I would like to safely remove this material. This material might be some type of epoxy. There are plenty of suggestions how to remove potting material (removing potting electronics). Some indicate that the chemicals in the potting might be harmful.
How can I safely remove the potting material? Through observation can I safely narrow down the potting material?
