It certainly depends on what you do with the truck, what weather it will see... If it is a good weather-only truck, going to a few shows, the rust should pretty much stop spreading: if the rust stays dry, it will not spread much, if at all. The surface rust on your truck may already be 20 years old, the body should last quite a few more years! I love patina, do not remove the original surface rust, it is only original once!
POR15 makes their paint-on-rust product in clear: it will keep the rust colour, "encapsulating" the rust to stop it; you can also easily apply it by hand brush or sponge; the finish will be shiny, though.
Maybe some other members know of other similar products, the main issue is to find something that will "stick"to the rust.
