Never had one removed. But I have 3 vehicles with wraps. One of which needs to have the wrap removed and I have looked into having my wrap provider do the job. If it's the same thing as with a vehicle (I'll assume that it is), it basically comes down to time. I wasn't told of the need of any special chemicals that are needed. Just heat to make the adhesive of the wrap part with the surface and time spent pulling the pieces off.
