OK, I added the brace for the rear lower skirt.
But the fender panel was still moving to easily between the that point and the taillight half way up or down depending on how you look at things, so I made a brace and installed it, it is welded to the outer sheet metal but floats on the inner panel.
I got 90+ percent of the bondo off this back panel and I used a hammer and whatever you call them hunks of metal to take the dents out from the inside and outside, I used a straightedge on the other side to see what the body panel curve is supposed to look like and I have it close, but in the end it will likely take me 10 tries to get it the way I want when I start applying and sanding off the mud, I really have not done much in front of the fender well and back of the door, there is one dent that I cannot get to the back side, I do not know how thick the mud is in that dent, I found it by accident, I kinda wish I had not found it, ignorance is bliss, I could not even tell it was there until it was too late.
I am working tomorrow, might not do much tomorrow except tend the garden, the corn is coming up, but the slugs are coming out also, they have already fell 3 or 4 corn starts, but I planted another 50 seeds where corn did not come up.
