I am starting on the rust repairs of my Formula and I know that I will have to cut out and replace some metal. I am removing all the sealer I can to see if rust has occurred, which it has in various places. The metal seems to be solid in the creases but I would like to stop the rust from coming back. Which Eastwood materials should I use and in what order. In this pic, you can see where I have peeled off the sealer and there is surface rust in this seam. The metal here seems solid and I will try to wire brush the rust as much as possible.
