Found a decent paint for less than a mil ?

I've got their stuff ina spray bomb on my manure hauling trailer. I'm rather happy with it. It's a few years old now and it's held up really good. I pulled the trailer out of my buddy's mother's woods, sanded and painted it, added some new tires, and started using it. It's not the shiniest stuff, but it is tough as nails and even with being left out in the full summer sun it's never faded. Again - no clear over it though.
