Reedster, the por15 does not have UV protection in it but since its on the chassis its no big deal. Its tough as nails and will look good for a looooong time. Its about $40 a quart but a quart will do two coats if you need to.
If you pressure wash it, rub it will still brushes you will still have 30-40 dollars in spray cans of primer then paint for the whole chassis so cost is sort of a no brainer. So, if you want something to last, tough and look good POR15 is the way to go.

PLEASE be sure to follow instructions and wear a mask even when brushing it on. Its some nasty stuff and you don't want it coating your lungs at your young age!!! Just follow instructions, keep it closed tight when not using it. Personally drill you a small hole in the can and pour it out in small amounts to insure it does not dry on you while applying and keep the hole taped up on the can......
Keep us posted on how things work out.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
