Be gentle, it's the first time I've welded on a car.
area under the battery tray had to go... there wasn't much left. Fortunately it was the one spot on the Donertona that wasn't rusted.
The next series shows some pretty scary business. My guess is that someone hit a parking lot barrier and popped all the spot welds across the bottom of the front cross member. The torque from the motor mount had torn the sheet metal all the way to the top of the member. It had also popped the spot welds in the corners. You could move the entire thing by hand. Yikes.
Welded up the two tears and completely welded in the corners. I also "replaced" the spot welds across the bottom, either where the original ones were, or along side the holes for securing the bottom of the fascia.
I'm definitely a welding novice, but I'm pretty comfortable with the penetration and integrity of the welds... had to grind off some bubblegum and reweld a few times. Will hit all these areas with seam sealer of course.
