I've got an "International", not IH, aftermarket spreader has to be 35 years old. Like Deerherd, I wash it thoroughly when I'm finished. Let it dry, then spray it down really well with WD-40. I then store it in out of the weather, upside down on 2 X4's to keep it up out of the dirt. Still looks, and works good, although the paint is getting faded.
