Then I welded in the left front corner and tack welded the front edge. There was rust all around the edges of the bootlid going further in at the corners and a lot further at the rear edge.
This work does take some time as I don't like bondo and would like to stay away from using it.
In the last picture you can see how I do it. The part is first tacked on. Then if filler rod is used during welding (sloppy fit) it needs to be ground so it does not stand much proud. And so the tacks and HAZ (Heat Affected Zone = blue) are hammered until the shrink caused by welding is stretched back out. This is not easy until you learn to read what the panel tries to tell you with it's buckles and "oil-cans".
Then the lid is offered up to the trunk opening to check the fit. In this case that was OK on first try.
After this the weld is finished between the tacks and the shrink is hammered out of it again. Finally it will be planished, but I'll leave that until all the patches are in. If you look carefully at the last picture you can see the weld seam of the front left corner in the light of the lamp. And it's pretty close. No bondo should be within reach.
