Maria, I know we all love your truck! So nice how you keep it un-restored and original.
I love your idea on the rims. While I don’t generally love fake patina, I feel for the purpose of matching up
to the look of the rest of the truck, this is a good plan. I experiment with various paints and finishes, by applying and
Removing when partly dried etc. mostly on wood projects to blend in repairs.
Try experimenting on a test rim. Maybe leave most of the rust, spray or brush on green, and spray it with solvent before its
completely dry, rub with a cloth. Or something in that vein. I think you can come really close to that look.
Cheap and easy! What they sell for John Deere Green now might be a little too garish .
Good luck, and be sure and keep that corn cob chucker on there!
