The finish on the Express is crap. This is what I do with mine. Use some steel wool and a bronze toothbrush and make sure you get ALL the rust off. Completely soak it until it is just dripping with oil. Leave it on for a couple of days then wipe off excess. I always wipe it down immediately after use and do the heavy oil soak periodically.
