Rust everywhere

[Fitzy1]

any one taken possession of a brand new jeep only to get home and whilst checking it out finds the undercarriage covered in rust ??


I've been asked to attach some Pics. Please remember that this is what I saw when I got home from picking it up. I've had plenty of new cars over the years and NEVER expected to see a brand new car in this condition. Really dampening my excitement of picking it up - and yes still get excited even though im 65!

Pics or video to see what you’re talkin about would be helpful

Normal. These things sit outside at the plant. Bare steel will get a coating of surface rust, unavoidable really.

Recommended undercarriage treatment to prevent it?

coat areas showing rust with ospho (rust neutralizer), and then hit it with something like rustoleum professional spray paint. etching primer it before paint if you're feeling crazy.

I personally wouldn't paint it, but instead treat it with something like Fluidfilm underneath once a year if needed. A lot of folks spray this, and similar treatments on farm gear, inside frames, on anything metal that gets frequent exposure. Fluid film will also keep it surprisingly clean and easy to knock off dirt or debris with a pressure washer. A lot of snow plow operators will coat their plows with something like this, front to back.

If you had SEVERE rust, which you don't, but I'd suggest POR15 as a protectant paint. I wouldn't be too concerned about it, but I would take measures to minimize it, especially in areas that see salt on the roads.

Im using CRC to prevent further Rust.

Never heard of ospho……. I’ll look into it.

Now my 2013 was terrible when I bought it. The axle tubes had rust and were barely painted at all. I used POR 15 on the areas that needed it and that seemed to work for me at the time.

My 2020 Willys, looked totally different in the undercarriage department. It was already 2 years old (almost 3) when I got it this year and while crawling around underneath it while doing the 5 tire rotation could really not find any unpainted or corrosion issues. Needless to say I was very pleased and surprised.
I did take 2 cans of Spray Fluid Film and coated areas I knew could be a problem area. Pretty sure this will be my last Jeep due to age and Health issues so I want to make sure when it goes to one of the grand kids, that they will have something they will enjoy.

It's a pretty rad affordable/effective product. I bought a gallon jug of it to use on all my projects. We are converting a schoolbus, and I used it on the floor to neutralize the surface rust before treating. Being able to put it in a pump sprayer like you'd buy for spraying weeds is a huge plus. You can get it at some ACE hardware locations, but also amazon.

You need to take into consideration that your Jeep took a long boat ride to get to Australia. Post some pics of it. There is a big difference between surface rust and scale. Likely just surface rust and one of the products suggested above will take car of it. It's also good to use it regularly since you live in a coastal area.

I undercoat all of my vehicles. I normally use Fluid Film. This year I used Surface Shield, its supposed to be a 2 year product. I have heard good things, we will see what a Midwest winter/salt caked roads do to it.

One thing I would recommend instead of spraying the welds with Rustoleum is to buy a can of it and brush the welds instead. It will look much better and last longer. Spray cans are hard to use under a vehicle and the overspray looks bad.

I recommend cutting it with 10% mineral spirits and using a narrow brush that will make it easy to just coat the welds. I used to build and paint water towers in my youth, so I did a lot of welding, grinding, blasting and painting.

Yeah when I've used Rustoleum in the past I use a big piece of card bord and held it above where I'm spaying underneath. But I didn't go that route this time. I just did the CRC coating.

But spraying it in a bowl and brushing it on is way better.

You can buy it in a can, like house paint. From small cans to gallon cans. No need to spray it into a cup.
