Take a length of Mig welding wire and feed it all the way round the pannel and pull it tight against the glue then take a 12V car battery and connect each end to the battery for a few seconds while carefully pulling the wire like a cheese wire then disconect and let cool for a few seconds then repeat the process keep doing this till you have cut through all the glue and there you have one panel removed without breaking.
The mechanic i spoke to has removed tons of glued on panels this way with no problems.
If anyone uses this technique let me know how it works with pictures if possible.
