Rust everywhere

[roaniecowpony]

Im using CRC to prevent further Rust.

Much better looking welds than my 2018 JLUR.

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.

at the very least the rust should be neutralized before covering it up with fluidfilm.

Since there’s no pictures. They’re all the same. Nothing to worry about

Big fan of fluid film…. 3 PA winter’s under my belt with an annual fluid film coating prior to winter, and undercarriage is good as new when you wipe off the film.

Guess it depends on the severity, but assuming it’s fresh off the lot, I’m going to assume it’s flash rust. Now, to me, that minor iron oxide layer acts as a moderate barrier, and isn’t crazy concerning, and the fluid film would finish encapsulating the flash rust as it soaks in.
If you had a substantial scale, I’d perhaps “neutralize” it, which I believe most of which are effectively a paint that chemically bonds with the rust and acts as a primer. Most are intended to be topcoated though. With an oil type saturated coating, such as fluid film, you’re removing the ability for the exposed steel to oxidize, but not in a rigid way. It doesn’t fail, unless it’s worn away. It also should repel water.
Now, if you “neutralize” the rust, I’m painting a broad picture here, and apply a coating that bonds to the areas in question, you’re placing a rigid coating material onto an unpainted surface, the exposed metal. Now, what if this unpainted surface has a crack form, due to a dirty surface, or thermal expansion differences, or running over a squirrel with a dog collar on, I don’t know. Then you have a coated surface, with a place for water to get into. Personally, I don’t like to coat anything without significant prep.
If I had rust to the extent that I felt like needed to be neutralized, I’d either replace the part, or prep it down to clean metal and respray it as close to factory as possible, and not use a rust converter. In my opinion, converters are utilized for areas that aren’t going to be properly prepped, or cut out and new piece put in, and are typically over coated with something else.

I am not an expert in rust conversion or products available, but I do have some experience and credentials for coatings systems in other applications, so that’s my opinion. ??

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.

Just saw your previous response. Not quite what I was thinking your were describing, but effectively the same scenario. Ospho is an acid, so you’re spraying your part with acid to neutralize the rust, then you still need to coat it, afterwards. Useful info, and I think your example of using fluid film afterwards would work, as I think the fluid film would saturate. I would be concerned about other items getting sprayed with acid and causing bigger issues.

I think in a case where you’re repainting, this would be a great product, I’ll have to add it to my reference base, as I have a few places I may give this product a try. Learn something new everyday!

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

That even better. I'll have to look for it. ?

I am perplexed!. A brand new truck and the customer need to spray it to protect it from rust!. Shouldn't this be done at factory? Doesn't every car comes with factory rust warranty ?

I have never had do this to any of my cars, and have never heard anyone need to do this to a brand new vehicle.

Is this unique to Jeep?

Totally normal, paint everything with POR 15 and you'll be good to go. Had to do it on my Redeye Challenger. I was pissed a 100k car came like that.

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.

POR 15 is great stuff! You can paint right over rust (if you're lazy) and beat it with a hammer. Tougher than a 10 cent steak

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.

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.

Thank you for the advice, the dealer had it fully redone with dry ice blasting and then recoating so it came up really well. was just curious to see if this was a common occurrence. I'm in Sydney so would've taken a while to get here plus salty roads and possible ocean spray, The rust was pretty bad so it was a rather unpleasant surprise when I found so much under the car especially when it was brand new and they are rather expensive over here.

Yeah, i was really disappointed and it took the edge of the excitement of getting a car I've always wanted. Thank you for the advice, the dealer had it fully redone with dry ice blasting and then recoating so it came up really well. was just curious to see if this was a common occurrence.

Mind you the dealer was really good about the whole thing as wereJeep Australia. They had it all sorted then gave me a nice credit to spend on accessories which was very appreciated by me.

They are expensive here too, glad they took care of you and did it the right way. Dry ice blasting is a really awesome process.

That was good of them to address that. Here in the US, the dealer would have said that they are all that way and it’s a characteristic of the vehicle.

Post some pics of your new Jeep when you get a chance. I can see you have different fenders and tires than US Rubicons.
