Not really. I've done some of my first cars with Bondo but not welding in body parts. I have restored some old tractors that I had to patch the fenders on. I bought a Miller 211 mig and with .023 wire and using gas, it is not too difficult to do. I am a retired Machinist and Millwright. I like to do my own work if I can. I did not paint my truck, my neighbor is an excellent body man and painter. I roughed it in, and he finished painting it. My truck already being a Five window cab, but, was rusted out below the back window, I had to replace the whole panel. If I was going to convert a Three window, I would just do smaller patch panels and not mess with the lower seam if it can be avoided.
