Rust Preventative Undercoating...
I am trying to figure out what is the best way to prevent future corrosion and rust from showing up on my 1997 F-350 7.3 PSD. I have just removed the bed, sand-blasted and painted. Looks new under there. Now, what is the best "stuff" to spray under there to protect it all?? Should I get WD-40 in a 5 gal. drum and run it through a garden type pump sprayer, or a 5 gal. drum of hydrolic fluid (H. fluid is low cost) and run it through a compressor/spray gun? Or something else??? I figure I would run this through my local area since we have to deal with cold winters and lots of salt!! I hate salt on the roads!!!

I did use a quality primer and paint, industrial grade. So its pretty protected for now. But I dont EVER want to see rust again. I just bought a heavy duty spray bottle and 1 gallon of wd-40 for only $16. Your right, it does wear off, but i'll hit it heavy once a month. However, every time they salt, I have to go to the spray wash and knock it off. Of course, that means another coat of wd-40. I have seen other stuff, amsoil makes something really good, but is EXPENSIVE! Eventually, i'll get a compressor and use the oil. Thanks!

I'd never admit to spraying oil on my truck because I wouldn't doubt it's outside the boundaries of the EPA laws. However, I too have heard that it works really well. You could get a garden sprayer and put used motor oil in it and spray the bare metal parts that you couldnt paint. Water would bead right off and it would last much, much longer than WD-40. I bet it would last about one whole season if you did it right, ie when it's dry and ready to absorb liquid......
There are more eco friendly products such as Fluid Film that I've tried that work well. It lasts a while....but I doubt it works as well as oil.

I've actually known old timers who wipe the frames down with grease. It's last awhile and it shines. I shake my head at it but can't laugh because they have some stock old trucks with no rust or rot. They other thing they do is squirt mystery oil in the hard to reach areas and places where there are plugs like rockers and door jams
