Spray oil underneath truck

[akronharry]

Want to spray the bottom of my 2005 Ford with motor oil. I have a gravel drive and keeping my truck on it is not great and it is beginning to get surface rust. Can I use 5w30 through my garden sprayer. SHould I heat it up first?
ANyone ever do this? Thanks in advacne.

I made the mistake of spraying diluted bulk engine oil to the underside of my 2 year old '64 one ton DRW flatbed Jimmy. The truck was used to pull trailers in and out of unpaved work sites. Man what a mess with all the dirt mixed with oil.
Doing any kind of maintenance under side would result in lots of black on my cloths.
After a couple of times under side I took the truck by a steam cleaner. I sure wouldn't recommend spraying oil under a vehicle if its traveling dirt/gravel roads.
We have about 6 miles of gravel road getting out in one direction. I've found under coating eliminates rust issues/noise to the body and frame. This part of the country isn't in the salt belt.

Not too worried about regulatory agencies. Just want to know if it works.

Used oil is acidic up to you

I have minor surface rust on the frame. The body has a little rust which will sand and try POR. I did buy "Fluid Film" and will apply when the weather hits 40 or above.
My biggest issue is that I have a gravel driveway and the truck is used once a week or so. I'm thinking of laying down heave plastic over garvel to help reduce water condensation. I know it is not a perfect solution, but really have no oter choices.

Some vehicles rust and rust thru so much faster than others and it's so obvious as to the difference when you put them on a hoist and look it over!

LOL

Yeah summers can be tough here but as far as comfortable, I'll take endless sun and 65-70F out here in Dec-Jan-Feb over what's available in other parts of the country!

It's all a compromise; when I lived in the Midwest and the East Coast, I enjoyed spring/summer/fall and tolerated winter. Out here, we enjoy spring/fall/winter and tolerate summer.

The best thing that I have found is just plain flat out keeping it clean. Every vehicle I have owned with undercoating rusted faster than ones without. I have a 1998 Chevy with 340,000 mile on it that has seen evey Minnesota winter along with gravel roads since new. The rocker panels are now rusted as well as the bottom of the doors and that is it. Frame has surface rust, but it is 16 years old.

You mean attached to a hose? Where does the water go?

And I can't imagine doing this sans hoist.

The road tube on my Cummins diesel does this each mile I travel automatically!

It's an older truck. Hard to know what surface rust is...without seeing it. In some cases 'surface' rust could be the harbinger of more rust underneath metal...yet unseen.

I have my vehicles Ziebarted...but when they're new. I think they do older vehicles.

Might be an idea to talk to a bodyman first...to see if it's worth it at this stage.

I don't know if spraying the underside of your truck with oil will help the truck.

Get some of this: POR15
It's popular with hot-rodders. Use flat black and brush, or spray, it on. Lasts a lifetime.

A little goes a long way if you brush it. It coats over rust (POR = paint over rust) because minor rust doesn't matter if it stops now, and most all paints initially stick to it just fine. The difference is that most paints, including intact auto finishes, Rustoleum, etc, allow water to penetrate their micro-porous surface and encourage rust to continue. POR15 is truly water-proof. The advantage to painting over rust (POR15) is that it takes very little prep, just knock the loose stuff off. What resists being easily brushed off is good enough to stick to. POR15 sticks better to rusty surfaces than smooth, so a de-glosser may be in order for present intact frame paint.

The downside is that other paint doesn't stick to dry POR15 very easily, and it fades if exposed to sunlight. But that is perfect for undercoat (in the shade). It's made of urethane and is very similar to the E-coat that all auto manufacturers now use to rust proof the new rust prone, thin, high-carbon body steels on cars. They should be using it on frames, too. These urethanes are similar to an epoxy, but only one part systems. Once the can is opened, they need to be used, as shelf life is drastically reduced.

Remember the silver, blue and white cars of the late '80's and early '90's that peeled? The prolific body rust was well stopped, but paint suppliers were wrong when they said that these specific colors would stick without a special primer. They didn't stick. And if you ever saw the paint lift, the E-coat was dark gray until the sun turned it light gray... faded. But never rusty.

This ultra-tough type coating is highly resistant to rock chips and can be beat out of shape with a ball-peen hammer and still adhere. Check out the web site. There are other urethane brands that are similar, Eastwood coming to mind.

Then why am I surrounded by "Snowbirds" already? :h

Here's a thought:

Move to Phoenix and never worry about it again!

:B

(Sorry, couldn't help myself!)

On a serious note, though, just bought a 14yr old Land Cruiser without a speck of rust anywhere. For vehicle enthusiasts, it's a little bonus of living out here and putting up with 115F temps in the summer.
