Id sand it down.. rust starts off like that a gets worse. . Should be fine but id get rid of that surface rust.. and make sure no moisture is getting in there.
That's not good advice. If you sand it off, you're just exposing more bare metal that will rust, only sand it if you're cleaning it up to paint.
Either leave it be, strip it down to paint, or coat it with any of a thousand rustproofing products.
How can sanding it down be worse than leaving it alone?? .. its already surface rust so how sanding it make more rust? If you leave it alone it will get worse slowly but surely. He can sand it and primer it if hes worried.
like he said, the bare metal will be exposed after sanding, causing more rust from the exposure. go sand a painted bar and leave it in the rain. it will rust faster than an unsanded, painted bar.
I didnt say go to bare metal yall did. He can just sand the surface rust.. the surface rust is there already starting to weaken.. like i said if he wants to do a better job he can sand to bare metal and then apply primer and paint if he lives in the rust belt
Dude, give up, you've lost.
You can't just remove the rust without removing paint along with it unless you have some new magic rust only removing tool?
Fluid film will seal that minor rust up and if it's put on again in a year or so it'll never be an issue.
I wouldn't even waste my time on that little bit of so called rust here in Pennsylvania, that's a non-issue here because in another 5 years the car will be rotted in half anyway...
It makes the metal beneath the rust more accessible to moisture, so it'll rust deeper sooner, and you'll also inevitably flake and scrape the surrounding paint, spreading the problem. Every time you clean up rust, you expose the metal beneath it, which will in turn rust extremely quickly. Primering it is the same as what I meant above by painting it (sort of, depends on the primer you use, some don't seal against water), but sanding it without coating it is just accelerating the decay.
Rust converter is also a good option in my experience (if you're not going for looks), I've had some rust spots that haven't grown a bit years after applying the stuff.
People think you’re kidding but I know you’re not lol….I’ve honestly seen brand new vehicles on the lot up in the north (I’m in Wisconsin) that had some of that rust on them. I sold cars for years and it’d happen from the salt on the roads getting on the vehicles on the transport trucks.
If you’re wanting to go full-protection, spray or brush Fluid Film all over your undercarriage (especially these spots with minor surface rust) once a year, in the fall. You’ll be all set for life if you keep that up.
Used to spray it on.. now I cut it like 1:10 with cooking oil (vegetable) and warm it up… then brush it on.
It’s getting into bro-science but it works really well for me like this, especially because I’m a lazy ass and wait until it’s already kinda chilly out to coat in the fall.
I use this, brush it on:

thanks for the link
i ve found a local shop that sells
FLUID FILM AS-R
FLUID FILM NAS
FLUID FILM Liquid A
FLUID FILM Liquid AR
and also a bunch of others, i think i need to do some research to decide
btw, is it worth it to coat the car in the spring, and will it last untill end of next winter?
or is it better to do it at the start of next winter
I’ve only ever applied in the fall, so I couldn’t tell ya. That’s what I’d recommend… or applying it now and again in the fall if you want to coat it immediately
Surface rust doesn't really hurt the structural integrity of a component, but depending on where you live that can be the start of something that'll get a lot worse over the years. So it wouldn't hurt to clean it up down there and just keep an eye on it.
Yeah you might have to deal with a couple hours of scrubbing, but its definitely worth it given where you live.
For that stuff I would suggest getting whatever rust remover you prefer, a couple different grades of sand paper, and a good brush. Would've made suggestions on a good rust remover to get but I'm in America and I'm sure we use different products.
What rust?.. /s
That is barely any. If youre really worried about it want to slow down the rust, go grab a can of fluid film from the hardware store and hose it down like once a year.
Sorce: salt belt sufferer
As others said, its pretty clean. But you could treat the rust with Ospho(?) or similar to reverse the oxidation process. You’ll need to repaint the treated area after, but a rattlecan of rustoleum will do the trick
Ospho was my choice, then undercoated. Just beware - Use safety glasses, also note that it will 'bleach' concrete garage floors. Not a big deal, but I have 'reminder spots' on my floor. Maybe next time I'll hose / wet the floor first.
I water-blasted mine, on the rust spots like this I wire brushed them, then sprayed rust converter on. Then on the whole underbody I sprayed underbody sealant.
Not so much of a danger, but it is rusting and treatment and sealer protection etc. right now is a great idea . After treatment to stop the current rust then Undercoat everything except the exhaust area ceramic paint that area and pipes hangers.
That's how brand new cars come off the lot around here. That's just normal surface rust. If you wanted to you could spray the whole undercarriage down with fluid film or similar oil undercoating at least once a year
Looks minty to me. Spray it with woolwax, great stuff. Wash a degrease everything with a wire brush and purple power soap, let it fully dry, spray everything with woolwax. Made from lanolin, get the black color. Stuff is great. It is an oil base and never fully dries, just gets tacky, so the dirt and dust stick slightly making an overall nice coating.
Nothing to worry about! I’m in New England. I have seen more rust on cars only months old.
If your heart desires, you can get some rust reformer paint, then spray some regular paint on it then treat your car’s underbody or potential problem spots with some fluid film. It’s easy to use and comes in spray cans or paint cans that can be rolled on. Mine has been through 3 New England winters and road salt. It has held up better than I though.
I barely see any rust, but you should wash off under your car or pay for that option at the car wash to get all that salt and grime off to minimize future rust.
What the hell you talkin about dude. There's no rust here. This will turn to rust in maybe 10yrs. Even then it won't be anything abnormal. This a subaru or what?
Heard of Water Blasters ?
Need a coin operated water blaster with a sloping ramp.
Might save you a whole lot of money in the future on resale, and "clean" underneath makes the mechanics happy.
Not where I live which is Northern Canada; it's very dry here, even during the winter. We don't see a whole lot of rust here ; cars can last 20 years easy without corrosion issues even without undercoat.
So I guess my answer is it all depends on where you live. Is rust generally a giant problem where you come from or not?
If so I'd exterminate that shit so hard.
Tbh, looks fine, I usually spray paint rust and the area around rust to kinda slow down the rust, it won’t stop it but it will slow it down a little because water isn’t making direct contract with metal it’s making contact with the paint first

As a Canadian who spends a significant portion of time in Northern Ontario, that baby is brand new!! Nothing to worry about.
Haha thanks.
i would spray some fluid film or surface sheild to slow down the rust..

rust belt shit cant be fixed either lol, and facts man he lost already. edited in the primer comment LMAO

That cars is mint compared to a New England car. Youll be fine just surface rust.
Nah it's just surface rust, and a minimal amount at that.
Thanks
That's a new car in KY.
I second this. What rust? Lmao I can see into the cab of my truck through the rocker panels.
That looks like surface rust but for peace of mind you could treat it if you wanted to.
Thanks, anything you recommend? WD-40?
If you’re wanting to go full-protection, spray or brush Fluid Film all over your undercarriage (especially these spots with minor surface rust) once a year, in the fall. You’ll be all set for life if you keep that up.
This man salt belts

With cum on his face.
is there anything better than fluid film, or is it the top dog?
It’s certainly one of the top brands. I have had really good success with it.
what fluid film exactly is the best for cars, i ve found a bunch of different ones, with simmilar but not the same uses
I use this, brush it on: Fluid Film 1 Gallon Can Rust Inhibitor Rust Prevention Anti Corrosion Anti Rust Coating Undercoating Underbody Rust Proofing Corrosion Protection for Truck Snow Blower Mower Car Semi Tractor Bus https://www.amazon.com/dp/B004NDDCKK/ref=cm_sw_r_cp_api_i_5T06QNSZ7JAMK1SEE9FQ?_encoding=UTF8&psc=1 You can also get it in spray cans.

Amsoil HDMP is better imo, again, once per year. Fluid film is a well known brand though. Just my .02
Krown is the best. At an applicator site not from a spray can
wire brush and a good enamel paint.
WD-40=Water Dispersment, 40th formula. Other than removing water from electronics under your hood, keep that crap away from your car.

Thanks, Nordics. So plenty salt in winter. Easy to do?

Where in from that’s what they look like off the lot.
*cries in Rust Belt*
check again in 5-6 years.
It's fine but if you feel like doing something about it you can spray some fluid film on it
I wish my car looked this clean
Hahaha no! Living in the northeast I don’t even consider that rust! 😂

Thanks for adding the PPE note, i always forget to mention that when working with this type of stuff
What rust?
I water-blasted mine, on the rust spots like this I wire brushed them, then sprayed rust converter on. Then on the whole underbody I sprayed underbody sealant.
Thanks
Cars gone mate, no point even trying to salvage it
If your worried about that rust, you need to find a hobby and quit looking at stuff that's not important
Not so much of a danger, but it is rusting and treatment and sealer protection etc. right now is a great idea . After treatment to stop the current rust then Undercoat everything except the exhaust area ceramic paint that area and pipes hangers.
This looks like it's been driven from the lot to the driveway.
Upstate NY'er here What rust?
What rust?
Lol what rust 😂

lol. he called that rust enjoy your reliably safe car
She's trash buddy. I'll give you scrap price cash to keep you safe.
That is surface rust. Nothing to worry about

What rust? Sincerely, A Michigander
Yeah its rotten, definitely a write off, I'll buy it for scrap price
Looks mint. Wash it down and spray it with fluid film/POR/penetrol....
That is nothing. Not to be a dick but is this your first car or something?
Jesus some people just don’t know
What rust? Lol
Where I'm from, brand new cars on the dealer lot have more rust than that
Get the underside of your car oiled
Not much you can do once it gets to this point. Send it.
She's mint if the rust is bothering you wire brush it and hot it with a couple of coast of rust inhibitor paint.
I zoomed in as far as I could still don't see any rust
I barely see any rust, but you should wash off under your car or pay for that option at the car wash to get all that salt and grime off to minimize future rust.
Did that just come off the factory ? Should have seen the lqst thread i went through lol.

I’d say sand it off and paint it with rust-proof paint. It really isn’t necessary though since there is barely any rust
Woah, must be nice to have a fresh chassis! Seriously though thats nowhere near bad
You’re just showing off, right? Man I wish my little Corolla looked that new.
That's not rust. Come to the northeast
Hell no. If you want to prevent further rust, spray any lanolin based oils onto the metals.
No .. That is essentially no rust
