You Truck people here know a heck of a lot more than I ever will. A Friend of mine told me that if a Truck has a lot of Rust under it, like on the frame, that spraying it with ATF and then drive it on a dusty road will really help. I don't have a clue. Has anybody else ever heard of this. Thanks, NL

 

Well, nothing get's rid of the rust short of removal. Probably the best solution for folks that live in areas that use lots of road salt in the winter is to apply more corrosion preventers (like undercoating) when the vehicle is new. Spraying oil around under a vehicle seems like a great way to make a gooey, dirty mess.

 

I have to agree with you. I did not have the chance, my LEMON was all rusted when I got it.

 

There is aproduct out called POR-15, it's to be applied right onto the rust, and claims to stop rust permanently. I have heard good things about the product, but haven't used it myself. It's advertized in my 2006 jeep essentials catolog from quadratec. it sells for 35.99 a quart in gloss black, supost to be good stuff, but not cheap, hope this helps.

 

Rust Bullet is supposed to be the best on the market. I can spray Boeshield on it too but that would run into money. It will take years for a frame to rust and I will be dead by then.

 

I've heard very good reviews about the POR-15 and am satisfied in my own personal use. My dad put it on his 87 Suburban that had 6" of suspension lift and 38" tires. That truck came from snow country and we knocked all the rust out cold with this stuff.

 

yeah the atf sounds like more mess than it's worth. I'd go with what these guys are saying, or just have it ziebarted, all they do is an oil undercoating. It won't stop the rust permanently, but it will help. costs a lot less too.

 

Thats a fun mess to clean off when you're trying to work on the tranny.

Just get it coated with a rust inhibitor when you buy it new, or do so when you get the truck, after attempting to clean off as much as possible.

 

NL,
I've sprayed the underside of a rusty truck with old motor oil (run thru a paint filter) and add some fuel oil (diesel fuel) to it, maybe 50/50 mix. It can be a messy job - but if you do it outside, when there isn't any wind/breeze, then start at the center of the undercarriage and work your way toward the outside rocker panels, so any drips don't fall in your eye, it isn't too bad of a job. Don't do it over grass, as the oil mist will kill the grass, do it on a gravel/dirt driveway. I used a 3' x 5' piece of cardboard to lay on while I moved around under the truck. A hand-held qt. sprayer works fine. I'd fill it about 2-3 times. I did the "drive on a dusty road" thang, but didn't find it make much of a difference one way or the other, so I don't bother with it anymore.

Sure, it'll smell like oil for about a week; it does get rid of a lot of squeaks and the first time you do it, a lot of rust "flaking and peeling" will fall off as you drive it. After a week or so, it has that 'clean oiled look' which I prefer over the dry, peeling rusty look....and it's cheap, a gallon of diesel fuel is only $2.80 and when mixed with old oil, a gallon will probably last for two "treatments". I give a 'treatment' to my old truck two or three times a year. Don't plan on doing any major work under it for about two weeks, or you'll get all oily. After two weeks, you can work under there without too much mess - it isn't bad at all.

I believe the oiling treatment slows the rusting process down, but as I'm sure you know, once rust has started, it'll keep going....unless you go with some high dollar cure coating stuff, there isn't much that will stop rust.

Good Luck!

Yeah, get oil and diesel in your groundwater.

great idea, also illegal in the United States.

 

HELLO - I'm not dumping it on the ground so it can soak down into the ground water, I'm spraying it on the bottom side of my truck!

It's the same thing as with paint, it's ok to paint your house, but you aren't supposed to pour paint into the creek....... Geeezzz.

 

ok boys it looks like we're back to enviornmental oil undercarriage boxing again. All those that think that oil undercarriage will kill all life on earth in one corner, all those that think oil undercarriage will make your truck last through the next millenia in the other corner and...........FIGHT!

 

here is an idea. though i dont know about cost and detailed procedure. but have the affected areas bead blasted (simular to sand blasting) then prime the clean fresh metal and seal it with your choice of under body paint. or rubber coat it (rhino line).

 

Oooo shooting beads around. That sounds like fun.

Not a bad idea really.
