The paint on that rig looks so good in the pictures that I hate to see where rust is bubbling through. I wonder if you can catch it at those spots and dremel it out like a cavity and then touch it up. If you did that it might buy you some time. Protect it with a good paint sealer and see how it lasts. If the rust bubbles occurred again, I would be tempted to go panel by panel and get each one in bare metal and get paint matched, even in a rattle can and repaint each panel as you go. Could easily look as good as it does now and cost pennies compared to a repaint. I'm concerned that your kids won't care about "adventures" by the time you get it back from the painters and you may have spent their college funds equivalent to get it painted.
