Here's a thread with some pics of a truck that was sprayed with orange tractor paint. Turned out nice! That's the exact color I'm looking to plan my rig.

That's my wife's truck. Implement paint is pretty easy to use. It's a single stage oil-based paint. You do need to add the hardener, because this paint took 6 weeks to dry enough to wet sand without it. I didn't use the hardener. This was my first time painting a truck, and am real happy with the results. As with all paint jobs, prep work is everything. I put around six coats on. One good thing about this paint is that it's available in spray cans for future touch-ups.
Good luck
