BE CAREFUL painting the seat post. In fact, I would simply clean it off with some steel wool and be done with it. Painting it is a good way of getting it stuck in the frame. (And the paint job will be ruined by the seat moving around and being clamped on anyway.) As for the bolts, if you can spare a few $, go to your local hardware store and replace them with stainless and never worry about it again.
I'm not sure about anybody else, but I don't generally put lock tight on any of the bolts on my bike and none of them have ever come undone. Whatever you do, don't use the red stuff.
