To truly stop all the rust you will need to try to flush as much of the 
salt and crud out of the way first. A pressure washer with a good source 
of fresh water to start off. Then inspect all the lines especially at 
clamps. If it is OK then you can start the coating process. Buy the 
coating in the color you want and some of the thinner. Mix up a batch so 
it is very thin and slobber it all around the tight areas so it can 
penetrate in as much as possible. Do this in any tight areas as well 
like door panels, bed seams, and all those places. Then use the normal 
stuff to coat all the rest of the frame, floor pan and rest. For the 
exhaust you may as well let it rust and when you replace it have a full 
stainless system installed.

  Once you have all the panels covered topcoat the surface with some 
undercoating to stop rock damage and the like. OR if you really want to 
stop the rust armor the bottom with a coating of bed liner over the POR 
instead of normal paint. You can even have some color matched (contrast 
if you want a two tone look) and paint the lower 10-15" of the panels 
all the way around as well. That stuff REALLY stops damage by sealing 
the surface so that nothing can get in. You can spray it smooth as well.

I did this a few years ago on a FD brush truck and it still looks like 
new. Pulled the box off and jacked the cab up as far as things allowed 
so I had better access and went to work. Works so well that a lot of 
folks are doing it on off road type rigs. I have done it on nice road 
rigs as well.
