I wanted to leave all the panels removable, especially the door skins. I felt sure if I bonded them on one day, I'd knock off a door mirror or the break the handle mechanism the next. So i attached the door skins with plates fibreglassed to the inside of the door skins - 8 of them for each skin - with bolts (or at the top and bottom of the skins, sleeve nuts) welded on. The edges of the Z3 doors have holes for the bolts to pass through. It worked out neatly but the jiggling and head scratching involved was lengthy..
