Default Undercarriage cleaning

Hey,

I'm from NY and our winters are brutal. Between the salt and Magnesium Chloride and Calcium Chloride that is sprayed on our roads, our cars take a massive beaten. From readings, the Magnesium Chloride and Calcium Chloride that is prayed on the thruhways are corrosion inhibitors...i'm not sure i believe it. I sure hope it is.

Either way, during the summer months I spray the under body down a few times. During the winter I barley get a chance to spray the under body unless i go through a touchless wash that sprays.

So i took a look at Larry's AMMO NYC Boost Winter Wash formal and his Aerator and I started to explore winter detailing and under body cleaning. My 19 STI undercarriage is pretty well covered and protected, however, the rear subframe and underneath the trunk is not.

my 02 wrx is interested in this discussion..

imgur is probably the easiest way to show your pictures, you need to get a direct link to the pic in order to put it in img tag. the instagram page is just a web page.

heres a direct link to your pic

I'm happy to see this thread too. I'm in Maryland- and we don't get snow like up north, but when we do, people are huge chickens and salt like there's no tomorrow. My work parking lot literally looks like the surface of the moon from heavy salt application.

My previous car was a Toyota FJ cruiser, which after 8 years had quite a bit of surface rust on the underside- and I didn't offroad it.. So far, my '14 WRX has held up, it's good to see others have reported they hold up ok to salt. I'll try to wash the undercarriage when it warms up enough.

I never liked undercoating applications- I've heard they can clog up the body drains and actually accelerate rust issues.. ALSO, I've not taken my car in for the recall- I suppose I should check my brake lines to make sure they're good.

Can’t recomend fluid film enough, this video was made by me, I will be doing a new comparison every year. If you have questions post them here.



I literally don’t wash my car all winter, if you want you car looking clean with fluid just do not get the undercarriage spray at the car wash because it will wash the fluid film off faster.

Rust is evil. It's especially hard to wash your car in these colder climates when it sits outside, too - then the whole thing just turns to an icicle over night and you feel like you're gonna break the door handles off just trying to open the door in the morning on your way to work.

The newer cars really seem to hold their own so much better than older vehicles when it comes to rust. You'll never outrun the surface rust on brake rotors, depending on how wet it is outside, and a few other surfaces, but the rest aren't too bad. If it's a car you intend to keep forever and ever, may be worth the trips to get undercoatings and what not, but even those can be a bit scary. I'm always worried the undercoater won't clean the car of just right before applying their coatings and then they just trap moisture or chemicals or solvents underneath it and allow it to continue eating away at the metal.

By the time rust will actually be an issue, it will be the 2nd or 3rd owner’s problem. Doubt you’ll keep the car long enough for it to be an actual issue. Drive it and forget about it.

Right, if you are going to get rid of the car in a few years it doesn’t matter. It seems at around the 10 year mark is when it can start to show on the body which will affect value pretty bad.

Fluid film doesn’t trap moisture in it wicks it out, so you don’t have to worry about it, even if there is some salt on the body the fluid film stops water and air from reacting with it.

But I'm the third owner of my car. And it came from New York Good bit of surface rust that I've been brushing at each time I go under the car. Nothing too deep. I plan on trying to get most of it off this spring so I can replace what is necessary and coat anything else.

You can also protect bare steel with light coat of motor oil.

In the spring I wash the undercarriage with my lawn sprinkler, then inspect for chips and cracked paint, rust on the subframe. I use Duplicolor engine enamel in semi-matte black as this paint adheres well to baremetal without primer. After cleaning the rust off with a wire brush and some cleaner (CRC MAF cleaner works great for this as it drives quickly), hit it with the spray. For areas where it's not painted, I coat the bare metal with motor oil with my disposable gloves. I just dab some on with my fingers, nothing technical or scientific.

My undercarriage looks good. Not perfect like my cars that I hibernate during winter months but still very clean.

You can pick up Subaru an OBD2 scanner on amazon for $20-$30. When your check engine light comes on, plug it in (usually under the steering wheel) and scan for error codes. When you get the code, you can get more information just by typing in that code with your car make and model into google. More than likely someone had the same issue with your car model. This will save you so much money in the long run because many of the repairs can be done just by looking it up on youtube. A 10 minute video ends up saving you hundreds on repair bills.

Remember, the only difference between you and a Mechanic is knowledge. The knowledge is now free, use google and save money on simple repairs. For those big jobs, you can hire someone to do an exact job instead of them telling you what needs to be fixed.


Good luck!

Edit:guys i found a site near me and it does free shipping too!! https://ljmcardiagnostics.co.uk/
Thanks you!
