Core support rust - fixable???

[BossHogg69]

Finally got around to finishing up what I started. I didn't take any pics of what I cut out, but you get the idea from the pics. I just drilled some holes in the patch piece and plug welded it and dressed it with a 60 grit flap disc. Along the bottom, already had holes from drilling out the spot welds, so I plug welded the patch piece using those holes. I tried to stitch weld it on the bottom too, but I shouldn't have, since it looks like crap. Good thing no one will see my pigeon poop welding down there! Btw, this is the first time I've ever done any welding on sheetmetal. I quickly figured out I don't have the patience for it.... I will say the Brother's patch didn't need much trimming, since the rotten spot I had was pretty big. It was a pretty simple fix overall.
