The video shows the process of removing the epoxy resin using a scalpel and a heat gun (fired up to 200°C). Removing it with a scalpel was rather destructing, but I did not want to use aggressive chemicals. The whole process took about 10 Minutes. The last minute of the video also shows some close-ups done with a cheap webcam, which was modified for magnification.
