Body Sanding

I'm getting started with the body sanding now. At the end of this process will be a sweet paint job but it sure seems a long way off. This first pic shows the most extensive rust rot on the body. This is the rear edge of the right front fender. The left side is not quite as bad. Then there are some smaller holes but they are in places that are not so prominent. I need to cut out this rust and shape some new metal and weld it into place. Then it will need to be ground down and hopefully I won't need 5 pounds of filler on top of it!
