I started working again, maybe a bit slow. I buffed the roof rail stainless for the driver side and started to install it. I found a couple of rust holes that I had missed.
I can't see cutting a patch 3/16" x 3" and installing it in this hard to reach place. The only thing that seems to make any sense is to build up the area with a bunch of short blasts with the MIG. Maybe not the best way to make the repair but it should work. The repair is kind of rough since there is no easy way to sand the metal. This is the result of grinding with a cutoff wheel. Good enough since it will be covered by the roof rail stainless.
The roof got too hot a popped the filler near the repair, so I had to grind a portion of the filler off. I now have to patch this.
While I looking a the quarter panel, it looks like the corner will require some work for the glass channel weather strip to install flush. Since I going to have some places to prime I might as well fix this while I'm going.
This is the starting point. It looks like the corner was hand formed and finished badly. The corner sticks up about 1/8" so it would require the glass channel weather strip to be bent if this corner is not corrected.
This is the finished corner. I had to cut a slit in the corner, bend one edge down and used the MIG to fill in the gaps.
