I'm going to be doing the same thing! Straps arrive today, going to paint them tonight, to install tomorrow. Hopefully the existing hardware stays intact!

A quick misting with rattle-can paint over bare metal won't provide corrosion protection for long. I'd suggest 3-4 coats of a zinc-rich primer, baked, and then several top coats of a good enamel, with the whole strap oven-baked at 250F after the last coat is dry.
