Body help/advice needed

I would be willing to help with advice. I own a spreed shop/restoration fabrication shop in Indianapolis,IN . If you would like to see my shop it's at the bottom of my signature.There is a link to the shops Facebook page.
So back to your project, I see several things that would be a red flag. First the repair panels look like they are lap welded? Really to replace as much sheet metal as you are doing the car should be sitting level. The picture of the trunk drop downs you have welded. First the sheet metal you are welding to is not clean. You will never get a good weld welding to contaminated material. Second the welds are to cold and the wire feed is to fast. The pictures you have of bare metal have rust pitting on the sheet metal. If you just prime over them the paint will fail in a short time. I would suggest getting the car blasted. Get it up on jack stands under the rails and square and level the body before you move on. Get the car in epoxy primer after it's blasted. Then start you sheet metal work. I will be happy to answer any questions you may have.
