Painting red iron buildings' purlins, guirts, etc

I need to know what would be the best paint to use to paint the red iron purlins, guirts, etc for my 30x50 building. I was going to put them on saw horses and spray them. My buddy wanted to paint them with tractor paint and hardener, etc. I just think it will take too long. Plus with the money I would have to pay him, I was thinking of buying a sprayer. Any suggestions on that. I want a quality unit. Anyway, let me know what some of you think. It has the red oxide primer on it now, a little discolored from sitting. Any help would be great.

I'd either use an oil based roof and maintenance paint or an Acrylic DTM. My preference would be for the DTM since you have a sound coat of what I'm assuming is probably oil based red oxide primer.

As it has been said,The red oxide you have now is a good base. From there you have a couple of choices.Heavy equipment enamel (oil base) Or a Polyurethane Enamel. Enamel will be the least expensive of the two. As to sprayers, Pressure pot comes to mind if you by chance have a compressor,220V would be more applicable to keep up a constant pressure.If not, a good single stage will suffice, but might be lagging in pressure. A cup gun will also do the trick. That to will need a compressor. Myself, I went out and bought a Graico mini turbo HVLP. 300 or so dollars,with a fine tip it might run you a bit more.That was quite a few years ago.Here is a link
They have gone up a little bit since I bought. Hope this is of some help. Good luck to you.
