I'm planning out my half restoration of my truck, body has a few quarter sized rust holes, and the frame has some solid surface rust. It isn't the flaky rust like most Midwestern trucks have, this one spent most it's life in Alaska. The frame is 100% solid, no holes. The pic attached is my frame. If this was your truck would you: take off the bed and cab, then wire wheel it down to bare metal, and seal that very well or jack up bed and cab, use POR-15 or Eastwood rust converter system, and seal over the converter Truck lives in Michigan but will never be a daily driver during the winter. Needs to last 3-5 years, until I've graduated college and have enough money to really bring the truck back to life.
