This pair of wheel weights was removed from a John Deere 110 square fender tractor that spent its life here in Colorado. They weren't rusty, but scratched. I stripped the paint in my blast cabinet using 220 grit aluminum oxide media.
I sprayed two coats of John Deere TY26268 Buff Primer and let it dry for about a week. I then applied two coats of John Deere TY25641 Ag and Turf Yellow and air dried it for about a week.That was about seven years ago. These weights have been in my shop for all that time. The part numbers are M11028 on both castings. If you are restoring a tractor for a show, these would be perfect.
