Wow Peter, brings back memories of my garage at the old house. Speaking from sad experience, use bungee cords etc to keep all the stuff hanging on the walls from moving about. My garage had almost identical wall hangings and shelving to what you have on he left side of the vert. One day I went from the house to the garage, hit the door button and the north wind roared in and dumped everything that wasn't tied down on my vert. I got a few nicks in the primer but fortunately no damage to the new top. I am now totally paranoid. LOL
