The second (passenger side) door has now been collected. I had always considered this door the worst condition, and while it is certainly in a bad way, I don't look at it with the same anxiety I did with driver side door. Still needs its share of working though!
This one has a small but quite defined dent on the outside, about 1/3 down from the top. This I will certainly lift out part way with a welded stud and slide hammer (or whatever I can find to use). When applying filler to a flat panel, it is best to try to support from the inside to stop the flexing that occurs. Repair work is more likely to be without a visible border once painted. Because the door lock access opening is not the full size of door cross section, I will use/insert a wheelbarrow tube and inflate to fill the space. An old panelbeaters trick, tought to me by an old panelbeater! Jeezus I hate panelbeating
I will also incorporate Phil's Technique to stabilise the inner hinge plate.
Speaking of hinges, the 2 from this door are in great shape, and wil not need to have any attention.
