It's not that I don't understand your position, it's just that I know how much time I wasted doing the same thing.

Then I had to go and swap the body....
Now I'm in the same position again and need to swap the body....
They rot from the inside, there are layers and layers of metal in most of the rot spots. If you fix the outmost rot it will just rot from the inside further up and when you fix the outer layers there is no way to appropriately weld to the inner layers that are part of the structural system. New metal on the outside is not connected to the right spots on the inside.
The important thing to note for outside observers of this conversation is that we are not talking about the kind of "rust" that gets posted up here in the "look at all this rust on my new cruiser" threads where there is some brown dust on the lower back frame rail. We are talking about the full-on, salt soaked disintegration of ferrous metals, holes right through frame rails and body panels rotted completely through all the layers, as in don't poke it with your finger or it will all fall apart RUST.
I've already told you in person (multiple times) how much of a rust bucket piece of c@#p your cruiser is, I should know, mine is too.
I saw you hammering away over there a couple times, but I was on my way out and told myself I would stop in on my way back through........
