Details- the seam that was eliminated ran into the end of the drip rail, and the roof skin flange was overhanging the end of drip rail a bit. The inside corner of the roof skin flange also didn't fit tightly against the drip rail, or the lower panel.






Inside corner tightened up with a rounded chisel and hammer.




Seam welded closed.




I also welded the roof flange to the drip rail so they wouldn't have a chance of separating later and cracking the paint.




Initial smoothing with 36 grit and a cutoff wheel for the tight corner.




100 grit.




DA sander.








Roof skin flanges welded via plug welds with a bit too much penetration.








Antenna hole was filled in.
