Por-15

Because of the amount of labor, time and money involved, I would top coat it simply because I would not want to do it twice. I've used POR15 before myself with good results. Although I think Rust Encapsulator from Eastwood is a little easier to work with.

I agree. I have used both and thought the Eastwood product was better. Less streaking and brush marks. Plan on doing the entire job because neither of them store well in the can. My car was rust free and I don't really like the idea of painting over rust, I just used mine on the underbody and then finished with chassis black.
