My tranny/TC area looked fine, it musta been all that oil flying around
If I had thought of it then I prolly would have cleaned it up with some degreaser and painted with Rustoleum. The bottom of the cargo area was another story, used a wire brush in a drill to get the rust off, then wiped it down with xylene and Herculined it. One gallon did the cargo area, up both sides outside the frame rails, and the frame up to the boxed part. At $99 a gallon you don't want to let any go to waste. A year later and no rust coming through yet.
