What can i spray over the surface rust on my axles and never worry about it again?

[XcumminsX]

OK this rust on my brand new axles is ugly! espicially because the thought of lifting my truck is coming to mind and all the good stuff underneath will be very visible to the eyes. What is a good product i can use to just spray over the rusted areas, and not worry about rust coming back threw and making the bottom look like a ford





Yes i know i am a neat freak!

I don't know of anything you can spray, but once I get my lift done I'm going to coat my axle with POR15, along with some of the frame.



I want it to look nice under there, but I know it will never be perfect.

A product called "One Step" will work. It comes in spray cans as well as cans for brushing. I rebuilt a 1962 M170 Jeep ambulance and used a bunch of it. My local Kragens has it, but I first discovered it in an automotive paint store. I suggest using a wire brush on the badly scaling rust first, no need to have clean metal. It will turn the surface a dull black once applied.

POR works well... tractor supply co sells 'implement' paint... I've used it on my jeeps and it keeps them from rusting. Comes in MANY different colrs (black as well) and it's cheeeep.

I touch under mine with some Rust-o-leum every couple of months and I have no rust to be seen. You have to get under the truck, but it only takes a few minutes... .

just move your breather tube around every once in a while

Something I have done was to remove the rust with a wire brush and spray semi-gloss black paint on them. It matches the factory color very well, and has stayed nice looking over the years. I also cleaned the drive shafts with a DA sander and painted them with a high quality paint, they look great.

LMAO :-laf



I tryed rust-o-leam (sp?) on the front driveshaft as a test and it didnt do very well. . Looks like the rust took over already. Next time i will try to use a wire brush and also sand it down clean it up then apply the rust-o-leam or another product.

rust

I've used a product called "skyco" purchased it from ACE

hardware, (if I remember it was only $3 - 4 for a gallon

which I still have 1/2. it is phosphoric acid and some other

"stuff" which will chemically change the rust into a coating.

I then follow up with a rustolium rust preventor, and then a top coat of semi gloss black if it shows. Never had a problem

or had to go back and re touch.



Under $10 and a couple of hours on a Saturday afternoon

should do the trick and allow you to "fix" all the rust spots.

By the way my first Dodge a 1997 was almost completely

painted on the underside, my 1999 3500 was OK mostly

the drive shaft and a couple of places where the factory paint

had been dinged, the 03 was the worst, driveshaft, springs,

etc, etc. They must be getting "stingy" with the paint???

Been using flat black rust-ol-leum for years. Might have to hit it a couple times a year. Good excuse for a look over underneeth anyway. Seems as if I'm under there for something or other a couple of more times a year as it is ! Never had to put more than two coats on the drive shafts,worried about balance you know.....

 

[thejeepdude]

I would try Rust Encapsulator by Eastwood... check it out here.



I haven't used it, but I've heard good things about it when compared to POR15 which is also great stuff. Supposedly the Eastwood stuff is easier to apply and stops rust even better. It comes in either a gallon can for brushing or a spray can. One spray can is 21 bucks, but that's not really too bad when you consider this is NOT just paint. Before spraying, though, you should hit it with the etching solvent... . if you try this stuff let me know how it goes since I've been contemplating doing the same thing.

 

[nkiewel]

What about something like a thin coat of Rhinoliner or something similar? Would that work?

 

[DPKetchum]

Deep mud a few times a month

 

[ThomasLawrence]

POR-15 really is great stuff. Be extra careful if you wind up using it, though... rubber gloves are a must, and watch where you put those hands. The stuff will NOT come off skin without removing a layer of dermis with it.



Actual label from POR-15 Top Coat can: "Contents partially unknown". Gotta love that!

Don't put it on your driveshaft without a solid plan. You wouldn't want it to become unbalanced by having a thicker coat on one side.

The bottom of the truck can succesfuly be protected with just a little effort. The simi-gloss Black spray paint holds up well and will blend in well with the rest of the frame. I never understude why they didn't go to Aluminum drive shafts like most other makes. Or at the very least, paint the damn thing. it looks awfull down there rusting away. You can paint it and have it last, but you will need to take the time it requires to sand ALL the rust off. I pu my truck up on jack stands and had someone turn the tires in the rear while I was under the truck with a wire brush/sidegrinder and a DA sander. Once it is down to bare metal, just prime and paint. This seems to hold up for about three years before it looks bad enough to re-paint.

The frame, cross members,trailing arms, springs all stay nice with just a spray of WD-40 and a good wiping off. I go under the truck and "Detail it" two three time a year. It is only about a two hour job.

Also you can take the easy way out and spray some Undercoating on all the parts and pieces under the truck. This seems to work pretty good at cleaning up the undercarrage. I don't like it because it is a bear to work around, it always gets all over you and the tools

 

[Hornball]

On my truck I used an ashphalt type under coating paint available in spray cans. It worked great. Just clean off the heavy rust and spray. My truck was rusty underneath too whan I got it and this cleaned it up nice. My has two winters on it and i haven't re coated it yet. Could use a little touch up to make it a little blacker but it isn't rusting.

"Don't put it on your driveshaft without a solid plan. You wouldn't want it to become unbalanced by having a thicker coat on one side. "











Thats what I was thinking when por15 and undercoating are mentioned. I don't think a spray can can affect it much, but I would think por15(and other similar products) and undercoating/spray on liner type things , could really affect the balance if not applied carefully.

 

[EMD-Run8]

3M makes undercoat in a spray can. I think I bought some locally for about $3 and change per can. It took six cans but I did a little extra around the fenderwells and the spare tire area, etc. It can be messy but it coated the underside of the truck real nice. I dunno about the driveshaft and the transmission. They look like h*@# like they are!
