Pete, I opted to leave this lower piece as is at the time so as to put the front end back together a little more quickly...(I may decide to put it right later on in the project....if it bothers me enough that is)...for now I can live with it...but thanks for the feedback....
The front wing was another spot that was not repaired as well as it could have been. Such as can be seen in this pic, quite a bit of bondo was used to fill the indentation in this outer sill area.
The gas welding done on this seam caused quite a bit of sagging and as a result it needed a lot of filler to bring the contour up it's proper location (another example of what you get when things are rushed I guess).
It seems that they didn't have time to apply any additional protection to the underside...only a single coat of primer was visible. Now one big benefit of removing the panel completely is being able to get the whole panel acid dipped. Removing this rust would have been a real pain to do in situ. ..
