cover AND stop?
In theory, once all of the water reacts with all of the iron in the steel, shouldn't it stop very soon after, as long as it's relatively dry, when you spray your underbody spray on there? Does anyone know what I'm getting at?

undercoating is bad because it traps any existing moisure underneith and any rust underneight, just having one pin sized area of rust will screw it. if a stone comes up and rips the undercoating ur screwed cause once water can get under that stuff its all over. I've seen what happens when undercoating goes wrong and it aint' pretty. if it is applied perfect to a perfect vehicle it ain't bad, but i'd go with por 15 or eastwood rust encapsulator or even maybe rust bullet on a truck of that age.
