If you have two pieces of metal apart you can use a "weld through" primer
that will allow you to coat the surfaces before spot welding back together.
This would be better than going back together bare metal.
I believe the vw body metal has a flash plating on it before its asembled.
I think there are quite a few good rust products like the Por-15 camp that
offer "liquid" converters that would work into seams well.
I had thought a bit of rust sealed off from any outside moisture would
"stop" or be severely "slowed" to the point where you could get the service
out of the vehicle anyway.
If you can get your "rust" to stay together another 20 or 30 years, you
might be able to trade your vanagon for one that can fly, who knows.
