    you can get it rustproofed where they spray the underisde of your truck with oil which coats it, not too expensive and some people swear by it,

    how about the rust that is already there? it's all over so just grind it all off or is there another way?

    I used black tractor implement paint from tractor supply. I just went over everything with a scotch brite pad and painted away. Been about a year and still looks good.

    the best way i say would be to get an drill and buy the wire brush (circular item with a bit at the end so it fits in the drills chuck) then remove the rust that way (wear goggles as well) then after your done that get an oil based lubricant ( or home remedy mix grease with transmission fluid and spray it on to the frame and stuff) in my experience i find the black stuff that looks like rockguard just peels of and makes the rust worse casue it holds moisture.

    do you park in a moist area or do you live in a state that puts salt on the roads during the winter. and as to protecting it you have a couple of choices take a wire weel to the rusty spots and pirmer then paint. you can also use undercoating. or you can pull it all apart and have the frame sand blasted then primed and painted

    Unless you get every spec of rust out, paint is just covering up the problem. POR15 is supposed to be a great product, but it's a lot of work to do correctly.

    You could use a product called Fluid Film. You can get it at a John Deere dealer or others. About $35 for a gallon. You can put it right over the existing rust. Any current moisture will get out, and the FF will keep it from rusting further.

    its going to be hard to remove all that rust out unless you take off your cab and bed and get rid of all the rust.

    Clean off the rust with a wire brush or even stuff called "NAVAL JELLY". Don't get it on paint it will take it right off. Then paint it with POR-15. It will be indestructable after that.
