I pulled the bed liner out of the farm truck (the 96) tonight. The bed ribs are rusted pretty good. I'm not finding it all that abnormal since it used to belong to a landscaping company, and they cut a hole in the bed liner for the GN, then all kinds of dirt, etc. got though the hole and was trapped between the liner and the bed.I pressure washed it and found that while there is rust, there are no rust holes in the bed yet.

I'm trying not to put too much money in this truck as it was bought to be a beater, and if I make it too nice I won't use it as it was intended. I know I could just leave it alone, but I can't help not wanting it to get any worse.

My questions:
1. If you seal up a rusted surface, not flaky rust, but surface rust, will that stop the rust from continuing?

2. If I put a spray-in bed liner, will that keep the rust from continuing? (It is my understanding that the spray-on company just scuffs the surface, they do not sandblast it)

I know that if I can spray it down with oil that will stop the rust in its tracks, but I will have to reapply it every so often.

Thanks,
Chris

 

I painted the steel floor of my cattle trailor with a rust preventative / stopping paint I bought at the local farm store. I just scraped off the loose stuff and rolled the paint on. Stopped the rust dead in its tracks. Been two years and nothing has come through.

I'm pretty sure the spray on bedliners stop rust also.

 

I'd sand blast the bed and make sure ALL rust is gone and then coat it in something that seals it. Like a spray in bed liner. Rust is the cancer of metal.

 

One thing I have been pondering for a while is, if the rusty area is sealed off, can it rust anymore? Sounds logical, but I was wondering if anyone else had such an experience.
Geico, do you remember the name of the stuff? I have some Naval Jelly I got from Napa, but I have not used it yet so I don't know how effective it is.

I hate to have to buy/borrow a sandblaster. If you've ever done it, you know that sand gets into places you never thought it could, on the object being blasted and on your person. I hate messing with it and try to avoid it where possible.

Thanks,
Chris

 

need only onething por 15 - napa has it

 

On the cheap?

Pick up a quart of Jasco Prep and Primer (Phosphoric acid)at your local Hardware store. 10-$15.00

Remove any loose rust with a wire wheel connected to your drill. Sand entire inside of bed

Apply Prep and Primer to all bare metal areas as directed let it dry overnight and recoat with same the next day.

Pick up roll on bed liner material at auto parts store $50.00 apply as directed.

I'll agree strongly with por 15

 

The best thing I have found is a product called RUST-MORT.
It converts the rust into a primer.
You can get it at any good auto paint supplier.

Por 15 is the same thing as Ospho. (phosphoric acid treatment). This will take oxidizing steel and turn it into a stable, primed metal which can be painted. Ospho is used in most body shops and can be found in many auto parts stores near their paint supplies.

POR15 is some good stuff

 

Remember that rust is the product of a chemical reaction. Namely the reaction of iron and oxygen to create : iron oxide (rust). If you prevent the oxygen from getting to the iron then the reaction should stop unless there is an air pocket.

I prefer the remove the rust and then paint method though. Better peace of mind knowing you painted over clean metal rather than hide the rust.

 

Wow, You guys know your chemicals!! I am impressed!!!

FYI, Ospho formerly Skyco Ospho was bought by Jasco in early '99.

Stamey, you now have several options to accomplish identical results!

Take from those who know and the last 5 posts here know!

You can do no better !! MYHOP

What I am trying to slow down/stop:



I'll check at Napa today for the POR stuff. Will Naval Jelly do anything?

Thanks,
Chris

 

Get in there with a wire wheel on a disc grinder, and remove all the crud, then go out and buy a good sealer. Bear in mind that the sealer is only goof the time that it is sealed. Once you cut through it when you throw somwthing in the back it has been compromised. I would suggest a rubber bed mat, as they tend to be a little less dangerous to the bed of the truck.

Just my .02

 

Yes Naval Jelly's chief component is Phosphoric acid. It may not give you the smoothest of results on the finish coat though and it is not made to be left on like the Ospho/Prep and Primer is.

The Prep and Primer chemically changes rust to an inert substance called Iron phosphate. When topcoated with a roll on bedliner product you should have no more rust problems.

Have you checked the underside of the bed?
