Kevin, what are your plans for coating your frame? If I am going to be welding on an area I'll take it down to clean shiny metal, the mig doesn't like rust. Otherwise I use the wirebrush to clean off all the loose particals clean it and coat it with Por-15 (It likes seasoned metal the best) If you have the means sand or media blast will clean it up nicely. The path we choose is usually dictated by time, money and rescources and what we are able to do ourselves. I travel through the week with work so one the weekends I have to divide my time between family, farm chores and my truck. I have had mine a year now and slowly making progress.
