Ok, here we go again.  This was easier in that I had a little experience now but harder because it was a bigger panel.  I had pretty much an entire quarter panel but didn't dare tackle anything that large and involved.  After all of the filler and paint was removed, I got a good look at exactly what was damaged.  I chose this pattern because it preserved the undamaged lines of the panel while allowing me to "hide" almost half of the repaired area seams.  This time, I cut out the damaged area on the body, using pneumatic scissors on the flat sheetmetal areas and drilling out the spot welds everywhere else with a spot weld bit.  This bit cuts out a plug around the weld but doesn't go through both pieces of metal.  A cutting wheel was only used where the scissors couldn't reach to reduce any possible warping.     . 
Once the old piece was removed, more damage was revealed.  The inner wheel well had been pushed in real hard and all of this metal going one way pulled the rear door post back a good bit.  A little hammer and dolly work got both areas back to where they should be.  No rust though, which is a good thing.  Now the patch panel was test fitted, marked, trimmed and repeated several times until the patch matched the body opening.  . 
I painted the rocker, inner fender, inner door post and the back of the patch with the rust encapsulator paint.  Then the adhesive was applied and the panel was put in place.  Several holes were drilled for rivets, but not nearly as many as the rear panel.  I just needed to hold a couple of areas together for the epoxy to set.  Everything was glued except the area where the rocker meets the patch and the very bottom inch or so of the trailing bottom edge of the wheel well opening.  I welded these areas.  In all, it matched up real well and I look forward to finishing up the body work here.  NEW!!  Well, the body work was more of a pain than I expected.  It finally came together and the finished product is seamless.  Mark it as done!!!
