Well folks, I'd highly recommend running a straight edge along a long panel before you start doing filler or you end up like me, removing a section that was "finished" but was not straight.
I noticed today while finishing up sanding around those darned pins that the passenger side had a nice bow to it. I had to remove a section of filler and run the pinner down the length of the body line under the pins on the passenger side 3 times to get the bow out. Then I had to remove a bit more filler because the heat from the pinner melted off sections of filler. Man am I good at this.
The picture doesn't show how bowed it actually was. I hadn't dug out the filler yet that was already 1/8" thick. The worst of the bow had to be about 3/16" or greater.
