I'm repainting in black - but for you, how about Fiskars Orange? What I actually mean is a light safety orange I live with in the CNC shop - and it's growing on me.
How to? Sand and prep as normal - I already have bought a 6" smooth roller with long handle to apply industrial enamel the local lumberyard carries - or epoxy if the wait time to harden and resand is reasonable.
I've seen results on the web - search "roller paint job" on mopar.org. Fantastic results consistently played down by the folks who invested hundreds in equipment for one job, or do it for a living. But that's how paint was done before spray equipment - apply a coat and color sand. It's labor intensive, it works, and it's great for those of us who need to paint a panel at a time. And it helps you correct all those little defects you'd live with if it was sprayed it and paid.
