I think you have it. Windows, doors, compartments, hatches and corner moldings will need to be removed on the sides you're working on as a rule. Don't try to cut corners here or it'll cost you bent siding. Once all the "stuff" has been removed from the wall, starting at the bottom, remove all the staples from the siding. Once those are out there's nothing holding the alum. panel and you can remove it. Repeat the process for the next panel up until the side has been stripped. As mentioned, nothing hard, just time consuming....
