Step 8: Remove the tape.
After the resin is fully set, carefully begin peeling away the foil/tape. If the foil was kept relatively smooth and the tape was not touching the resin, it should peel away from the hardened resin easily. The only area I had problems was where some resin seeped between overlapping ends of the foil/tape. Also, there were a couple of spots where the resin seeped over the edge of the blue tape slightly. These were both easily remedied using a hobby knife.
