Hotboyrn84, I've been looking at your pictures which have generated a few thoughts. It appears you have the car raised and off of the frame. Depending on how you have the body secured and braced, I am concerned about how much torquing and twisting is happening with the body. If the body isn't secured and oriented flat and square while you fabricate, weld, and make inner structure and outer skin repairs you are locking-in this configuration. This outcome may not become evident until the body is lowered back onto the frame and hinder your body mounts. Another point is how far away from the rusted areas you are making your cuts. The standard I've used and was taught in body fender repair classes is 2-3 inches at a minimum. In some of your pictures, the cuts are right next and on the edge of the rust. I can understand your desire to retain as much original metal and, thereby, decrease the size of each repair and patch piece. Unfortunately, leaving these underlying rust-damaged metal and covering them over with body filler is not a good solution nor approach. Your goal in doing these repairs is to do it once!
