Prime with zinc chromate and then paint like anything else. Should be able to buy at any marine or aviation supply store.
Great looking work, might want to consider a runner on each side from the top down to the front to protect the windshield from tree branches. Mine takes a pounding and I wish I had something to protect my glass.

Thanks for the info. i have considered the bars to protect the glass i just haven't commeted to a style yet. i am a firm believer of function before form but i don't have alot of brush issues where i go and haven't liked the look of any of the bars i have tried to make.
Take a look at endura paint. It's one of the best
If you want to get really carried away, but durable-
Etch it with Alodine, use a 2 part polyamide epoxy (zinc chromate based), followed by a topcoat of your choice.
nothing to add on paints...
