Maybe it's called something different where you are? Oil spraying? I grew up in a mechanic family and we do this yearly on all our vehicles.

I grew up in a small city in the Central Valley of California. There was a lot of agriculture around me, so I can see if they did that, but I did not lol

Undercoating is practically a must if you are living in a snowy country that uses roadsalt in winter.

Live in Minnesota and we’ve never done it to our cars but we should

Ah, well that explains it. No snow whatsoever in the central valley lol

In nothern europe, undercoating has a 50’s sound to it.

People specifically buy cars from the Central Valley due to them being usually rust free even when they are 20-30 years old. With no undercoating needed other than the usually soundproofing coating.
The coastal regions get salt air.

Huh, I never thought about that. Interesting.

I live in south Texas where we have an excess of humid days. Frame rust just doesn't happen here. There are loads of 20-30 year old cars that are falling apart but have solid chassis.

Um, no. It's the salt.
Only recently did they start using salt compounds in soaking-wet Washington state...and only recently did undercarriage rust start showing up more than superficially. Magically those both correspond.
Old-school undercoating is a huge nasty problem of itself but that's another debate.

Can confirm. In NS, we use tons of salt, and the damage is very apparent.

Fellow WA state here. I noticed we recently started salting roads and I am pretty pissed about it. It doesn’t help, is bad for the environment and horrible for vehicles. I don’t remember voting for it.
TraditionalSell5251 t1_iydjiut wrote
It doesn't help? Was under the impression the salt added traction, lowered the melting point, and absorbed some of the water, is that not the case?
BabyTRexArms t1_iydqq2t wrote
In theory, but the drawbacks heavily outweigh the benefits. They oversalt the roads here, and that mixes with meltwater and runs off into all of our water sources. Not to mention how bad it is for pretty much any surface whatsoever lol. I've never benefit from salted roads, sidewalks, anywhere.
LukeyLeukocyte t1_iyfawrd wrote
There may be bad side effects, but those roads and sidewalks would be FAR more treacherous without the road salt, no? Do you live in an area where everyone has tire chains? I guess that would make the salt less-needed.
​
I always think about all the damage salt does (especially since my job is to fix parking garages - which get destroyed by road salt) but I always wonder how the heck we could live without it because society would come to a screeching halt when snow hits in my area without it. Would love an alternative but it seems far away.

I live in a very wet and humid area, undercoat isn't a think here. I think someone just wants to sell you something.
LipTrev t1_iybuj8e wrote
This is just plain false.
Places with lots of rain, lots of humidity, and no snow, that are far from salt air do not rust anything like cars that drive on salted roads, or live in a salt air environment.
And those two (salted roads versus salt air) have different rust patterns from each other.
The linked article is a Canadian website. If they lived in the American South they'd know they were lying.

I second this. Ireland is much wetter than England but we don't ice our roads like they do and the main issue with imports is rust. Changing the brakes on an English import is a nightmare due to rust where as there's almost no rust on Irish cars
RedSonGamble t1_iyassp1 wrote
Cars don’t rust as much as they use to. Mainly bc of lighter metals and more rust resistant metals.
People that religiously get their cars washed will hate this post though. I have a decent scratch on my car that goes to the metal. I live in Wisconsin. It’s been two years and it’s finally starting to rust. I should really fix it.
CanadianFooBarMan t1_iybhyt5 wrote
The eternal debate of spring undercoating vs fall undercoating.
IMHO, you only really need to get your car undercoated once every 3-5 years, as undecoating is not meant to be washed off/cleaned, and it doesn't really matter when you get it done as they clean the underside of your car anyway before applying it. What you do want to get every year done is your car rust proofed, where they spray rust proof liquid into the nooks and crannies of your car to push moisture out, and it's debatable when you want to get it done, but usually people do this in the fall because otherwise the weather warms up and that thins the coating a lot.

This is just wrong. I live in FL, which is a giant humid swamp. Cars last forever here in terms of avoiding rust, and no one get undercoating.
Same for some other states.
Brokinnogin t1_iyf2sg5 wrote
Its more that vehicles in areas with salted roads have this issue once the salt is hydrated.

how much does this undercoating cost? asking for a friend with a car barely worth protecting
HeySquirrelFriends OP t1_iyb7dts wrote
It varies on the size of the vehicle, but most places are generally between $130-$160 CAD.
AirborneRodent t1_iybheb7 wrote
Too much.
Undercoating for years was synonymous with sleazy car salesmen selling you extra features you didn't need. "Bought the undercoating" was an idiom that meant you got swindled.
It's mostly forgotten today, because the metal and the paint on modern cars are far more rust-resistant than they were 40 years ago.

Most modern cars have frames and bodies that are completely galvanized with zinc, so corrosion doesn't spread like it did on older cars.

Only true in places without road salt or salt air.
