Here is one of those wrecked areas where there was a large gap.
I decided to use some tig filler rod to help fill the gap and weld over top of that.
Cranked up the welder to insure I was melting the rod as well. I was very surprised that it actually worked out well. I don't think it was any better than the "padding" technique for gaps, but I could see using it to help recreate damaged leading edges and curves? But, IDK
