I have My JK 2008 for exactly one year (August 31st to be accurate).
I had a anti-rust treatment from the dealer one week after I got it because I knew the winter conditions we are facing in Canada.
You can see that it is very efficient! :pissed::devil:





I went to the dealer 2 weeks ago and you know what? this rust is Normal!! :devil::pissed:
I have been told that the treatment is only for the floor and that it is normal to have rust on the muffler and driveshaft and transfercase...

Anyway, even without the treatment, I think that it is really not normal and not acceptable to see this amount of rust on a one year car even in Canada!

I would like to have your comments!!

Thanks

At the least...I would spray the axles, etc w/ WD-40. The exhaust tho...looks like another winter and it will develop some "extra flow". I've seen under many JKs and this is the worst rust I've seen. Most of the JKs Ive seen, however...have been in Texas, where we don't see much road salt. Maybe some will say thats normal...dunno?

Wow that sucks....

If I were you... I would get the frame off the body and get it cleaned up asap... obviously the factory powder coat sucks... At least if you strip it down and rust proof it yourself it will last a lot longer..

I live in CO and am not looking forward to rust...

Good luck to ya..:beer:

FWIW, I seriously doubt that it's powder coated. My paint came off the rear axle while hitting it with the sprayer at the carwash. I agree that the op is better off doing his/her own rust proofing unless they have the energy to fight Chrysler on this.

I have a small can of flat black Rustoleum and one that's glossy. Once a month or so I get under the Jeep and look for any rust spots. If I find any, I just brush them off quickly (I don't even take much time to clean them up all that well) and use a paint brush to paint over them. This seems fairly effective. After a couple of times, most of the rust has been treated and so far I don't see it coming back. Using a brush, I don't have to worry about overspray, etc. and I don't really care that much about how it looks. It might be worth a try.

I won't say that this is the best solution, but when I bought my TJ I was living in Minnesota. They love those chemicals to keep the roads drivable. I had the Jeep for just a few months before the rust was popping up. I used POR-15 to take control of the rust and give the undercarriage rust protection. It is fairly expensive, but it worked very well. After a beating in a Minnesota winter it didn't have any rust.

Ah hell !

Manu17e:

Hi, fellow Canuck here.

Very frustrating to see the rust. One of the f'ing joys of living where they use salt is rust.

Rustolium, Tremclad's anti-rust paint, the POR product mentioned above, Ziebart (in a spray bomb, $17.00 per can) any anti-rust paint or a gallon of roofing tar (Bulldog) are the only products that will help now.

The stuff that the dealers use (just about all of them) is at best worthless, but a wonderful revenue generator for the dealer.

As the guys have suggested, before the really cold weather hits, find a dry day, crawl underneath and spray the entire bottom (body and frame) with the anti-rust paint, Ziebart or product of choice. If you want to really do a good job, use the Bulldog roofing tar, a paint brush, cloths you never want to see again and coat every thing in sight except for the exhaust system, cat. converter, and braking system.

For the muffler (made of relatively low grade stainless steel), sand it if you want, but I used a high temperature manifold spray paint (black) and painted it. One it made that huge silver thing seem to disappear, and two it protects it from the rust (but only for a couple of years). Rust in our "salt-land" is inevitable.

Hope this helps. Not what you wanted to hear, but...

It's not a problem here Airric because it’s very dry. Just take it to a car wash and spray the underneath off between major snow storms to get the chemicals off.

I get some very light rust and get under it about once a month and rattle can anything I see which is mostly scrapes and dings from wheeling anyway.

That really Sucks. Take care of the cancer before it spreads. This weekend I saw a Jeep Wrangler for sale on the side of the road which Looked really nice from the road.I stopped to check it out and when I crawled underneath I could not believe the rust that was Present.I would have really been scared to take it off road.:shaking:

I just tried some RustBullet, It dries silver and is hard as nails; it is supposed to be the new POR15, and has the price to match.

In Michigan rust happens, I also drive down a minimum of over 2 miles of dirt road to get to pavement so we have salty mud too. I can't say that I have seen a vehicle that wasn't treated aftermarket that wouldn't get rusty here. Few days ago it was 0 degrees F and yesterday it was about 60 degrees F which also leads to condensation everywhere.

I had the vehicle coated by Ziebart, they did miss some panels and I had to take it back. I think it was worth it for the body panels if the shop does it right. One thing that they don't do is spray inside the frame, only the outside. If I had to do it again I would have not had them spray the frame at all.

After Ziebart I used many many cans of Professional Rustoleum, I paint alot of rusty stuff on the farm and I do see a benefit in wear resistance over regular Rustoleum. I also taped the nozzle down and stuck it inside the holes of the frame to fog the inside, started with primer so I can see if it was getting coverage.

I have used POR15 many times, it works great if there is rust, if the metal is clean and painted I find that it tends to peal when scraped. It is a great product for rusty stuff.

Other problems that I saw quickly that needed attention were holes in the frame. The frames need holes to breath and drain but not that many. The main ones that need to be covered are the one behind the front tires, on my muddy and gravel roads I would fill the frame with mud and rocks in no time.
I used wide Guerrilla tape to cover them and painted over it to seal, I would like to find some plugs for long term but it has held up well.

I also noticed that the rear fender wells didn't have as much coverage as I wanted. I was pulling rocks out that were shot between the rock rails and body from the rear tires and while off roading the rear tires threw enough sand to push up the foam behind the fenderwel and fill behind the tail lights with sand.
I used small black Rubbermaid US made trash can to extend the plastic down. I sealed the seams with tape and painted over it. It’s not at all pretty but isn't real noticeable and serves its purpose.

The front edge of my door hinges were also chipped to the metal from my front tires throwing rocks. Mud from our roads also would spray up to and on the rear side windows. A friend bought me Mopar mud guards so I installed them. They looked much smaller once installed which is good. They were a little loose - attaches securely to the fender but the whole assembly didn't seem real secure. I drilled a hole in the guard and rock rail cap and installed a push lock plug. Much more secure and it does keep alot more of the salt spray off the Jeep. I may need to remove it or modify it before I do hard wheeling (it held up at Silver Lake Sand Dunes) but worth it to install during the salty winter.

You just got a bad job. I took mine to a local guy who disassembles the vehicle top to bottom. The only thing with any rust on mine is the muffler.
