I think the dark oxide finish is Fe04 which is formed during the process. I used the cider vinegar molasis bath for small parts and had the fenders, hood metal and wheel hubs blasted. Everything else gets oven cleaner, wash and a spray of phosporich acid ($10 HOme Depot). Then a wipe, dry and prime.
Its more than I intended but I figured I would take the time while the tractor is down. Once done it'll be back to its current duty of brush hogging and a bit of cultivation.
