Struggling with my project

I would not fret the bodywork. The body shop will most likely start at the front and work back. So pick a front corner and work back. The skill will be actually identifying highs and lows with your hand. Spend some time at several of the local body shops also. Because materials and products always change there are going to be several different techniques. That can be confusing sometimes. Be thankful you are not in New York or the "rust belt". There is a nice tutorial in the body and trim forum here.
