OT: painting my new pipe fence

I have a new pipe fence that I need to paint. Most of the fence was constructed with "new" pipe with little or no rust. The pipe used on my gate supports is severly rusted. How should I proceed in preparing the pipe and what type of paint/primer should I use.

I've been told to use TSR from the homo depot which I think is some diluted triphospuric acid stuff. I should let this dry and then prime and paint. I'm thinking of using rustoleum enamel paint and primer that is also available at hd. But there is also an Oliver Tractor color of paint at Tractor supply that I think would be a neat color. Does anyone have any experience on using either of these brands of paint.

Thanks,

In the oil patch, we would use what's generally called "surface tolerant" epoxy. I would at least wire brush the gate portions that are pretty rusty and then wipe with some hot thinner to clean. For the new pipe, if its dry and not covered with dust and dirt, you can apply the epoxy directly. Two coats are better than one but if you have a good sprayer, you can apply a fairly heavy coat and be done. Epoxy is a "hot" paint and is self curing--like fiberglass. Some brands sell two part mix and others sell as one-part already mixed and ready to spray. The paint is very durable and is extremely hard after curing. Enamel is easier to apply and cheaper, but not as durable. Only complaint I have is that the expoxies tend to "chalk" after about 10 years in the sun. Follow all safety warnings and use a good respirator and good ventilation.
