Wish I knew someplace good to buy single-stage paint economically
John Deere sells Black and Red, (white, yellow and green too) as their equipment enamel. Synthetic Enamel
Here is the Synthetic Enamel Hardener that works with it. Makes it dry a lot faster and lots tuffer of a paint film. Something you can work with if things go wrong.
Here is the JD Paint Thinner for their Synthetic Enamel finishes.
Available at JD dealerships and also can order it in from online.
Ebay . . etc.
Hardener is from an independent supplier.
