Most of the shots you refer to were just the preliminary cuts. Those cuts were adjusted and expanded to remove the rust back to sound metal. Some edges you see surface rust and was ground out before welding.
The ("Looks like there were some shots where you left a few inches around the cut.") areas you refer to is not rust but the colour of the rubberized coating on the underside of the car.
I didn't post shots or have shots of every change, they were just to lay out the process.
I've got over 3 weeks (of nights and weekends invested) in this repair so far.
Yes the arches are a major pain, lack of space, hard to see and work while rust and dirt keeps falling in your face. :mad:
Too late for me but a friend is buying a bead roller to simplify the fabrication of new arches.:p
Thanks for the observant commentary.
