OMG!!! $100 a GALLON???? That stuff damn well better be the best around. That's an obscene price. Personally I'd just go with a 2 part epoxy coating at about half the cost.
Joker, when you are painting that tube, make sure you paint the INSIDE as well as the outside. Metal heats up and the air inside the tube expands... then as it cools it draws in air from outside... and that air is laden with salt. So, over time, the inside of that tube will rust out... and it won't take nearly as long as you think, cause you'll never wash out the inside of the tube, so the salt will lay inside there and do it's thing. That's why hot dipped galvanized is worth the few extra bucks. By the time you add in the cost of the paint, and your labor, most times you're spending more for bare steel than for galvanized.
