Nice progress your making there, it's always nice to be in the dry when doing stuff like this
I was going to mention the seam welding too, I'd do as Nugsy suggests and weld it with a series of spot welds, but allow the panel to cool between welds. Start with a spot every 6 inches and slowly work your way across the gaps, it's very boring doing this, but the result is much better.
