Anti Rust Coating in Car. Worth or Waste of Money ? Explained

3M Anti Rust Coating in New Car. Is Anti Rust Treatment Useful, Myth and Reality with Prices, Benefits of additional Coating on Car

 

Anti Rust Coating

  • Are you been Pitched by your Car Dealer or Workshop about Anti Rust Coating ?
  • Are you been told that your Car Under-body will catch rust in Monsoon if Coating not done
  • Are you in Doubt that whether Anti Rust Coating is Useful for your Car ?

Here we will demystify your Doubts on Anti Rust Coating including Utility, Benefits, Pros and Cons

 

Know your Car. How Rusting Happens

A Car Body is made up of several Metals with

  • Cast Iron and Advanced High Strength Steel makes up almost 65% of Car Body Weight
  • Other Metals used Aluminium, Copper are then Predominant in Manufacturing Car

Rusting is layman language is Corrosion and Corrosion is what the direct reaction of Iron and its Alloys when comes in contact of Water or Air Moisture. So, essentially to make it simple - Any Iron material when exposed to both oxygen and water is bound to rust - unless a preventive coating is applied on to it. 

See the Rusting observed by user, when he went to bought a car and casually checked underbody to find Rusting sign Visible

So, prima facie it seems that Anti Rust Coating is what an essential part, But is it actually Required

 

Reality Vs Myth about Rusting and Anti Rust Coating

Do note that a car when Manufactured in Plant is made with

  • Galvanized Process on Cast Iron and Iron Alloys
  • Industry Approved Coating

Galvanization is basically using Advanced Zinc Coating on Car Metals. Zinc is what Anti Rust and these highly specialized coating prevent car under-body from Rusting.

Enough Protection done through Industry approved Coating Solutions by Car Manufacturer so that Car Under-Body, Doors, Boot, Body Panel do not get impacted by Rusting. Also, Galvanization is done with Rust Resistant Alloys to provide long lasting Output without any Corrosion.

Now - enough Protection in form of Anti Rust Coating is been done which can be offered for all regular drive conditions at Manufacturer end, and as such no need for further add on coating

 

But Still Car Catches Rust. Is Anti Rust Coating Useful

Instead of saying whether Useful, should we answer that - additional Anti Rust Coating does no harm in New Car. Been- Car is made up of Top Notch Precision and the fact that Car Manufacturer - already uses in Galvanized Material with Rust Resistant Alloys and Enough Preventive Coatings.

For Areas with Moderate Weather, Rainfall - there is absolute no need for Anti Rust Coating. Its just waste of Money !!

But, for Coastal Area Regions or Areas with Heavy Rainfall

  • Due to higher than normal Moisture
  • Areas with Higher than Expected Rainfall
  • Sea Water Proximity - The presence of salt acts as a catalyst, accelerating the corrosion chemical reaction process.

Any additional Under Body Coating, if applies does no harm. further add on Coating (if offers you peace of mind) then go for it. But, Do note that your Car Under-Body is already given enough protection by Manufacturer end and expecting much from the additional Coating as Solo Protection may just be raising the expectations too much

The Brand New Car which got Rusting was due to in Contact of Water for longer period of time. Had the car got this Dealer Level Anti Rust Coating too - it would not have made much difference in getting Rust developed on it.

Still - If you feel to spend an extra small amount as been finicky for extra care - The Costing Part is generally Rs 2000 - 3000 for 3M Body Shutz Anti Rust Coating or Rs 2500 - Rs 4000 (Anti Rust Coatings as offered at Dealer Workshops) - Prices varies basis Body Design of Car

To Re-iterate - there is no harm, it just adds on a layer on already the existing Protection levels, but point is no real benefit of same in Brand new car

See this Video -

 

Though - to Differentiate from League - if you Intend to Hold Car for 10 Years or more. May be should go for Anti Rust Coating at the end of 4th or 5th Year. It rather involves slight complex task - been the Under Body needs to be Scrubbed, Cleaned, Degreased before applying Anti Rust Coating

Also - would rather be advisable to go in with Experts who can do detailing of Underbody - instead of only just simply spraying the Coating Chemical.

 

3M Anti Rust Coating or Dealership

Even the Dealerships use in 3M Chemical - so it really does not make Difference - from whom you get Coating Done - whether at 3M Store or at your Car Dealership. Like - Windshield Experts are the best for Windshield replacement, 3M is best for Car Body Wax, Under-Body Treatments - its there Forte Expertise.

Prices Varies based on Models at 3M. To give Indicative Estimate 

You can get details on - 3M Car Care Price List

3M Anti Rust Treatment with 5 Year Warranty Hatchback Rs 3000 - 3500
  Sedan / SUV Cars Rs 3500 - 4000
  Luxury Cars Rs 4500 - 5000
  High End Luxury Cars Rs 5000 - 6000

Do not miss to check on Warranty T&C - comes with 5 year Warranty

Congratulations on your new car, drive safe.

Yeah I recommend Extended Warranty if there is a cover on some of the wear and tear on your vehicle parts, especially like the Shield of Trust from Hyundai. And I got it for free (costs 6K) by negotiating it for some lame seat covers. I suggest you to negotiate it for some dummy accesories which they're offering for free if possible.

Anti rust coating , if they're quoting it for less than 3K with the warranty then it is a win situation for you.
Happy helping cheers ??

I purchased underbody coating (due to their relentless pitching) before delivery of my Honda Amaze vx CVT

Now for first service they are pitching silencer rust coating 1500rs and door internal panel protection 3000rs.
Are these coatings necessary for a new car.

Thanks for the information. I have got one of my car underbody coated by 3M with their 5-year warranty coating. However, they have a policy that if the car underbody is already rusted the company do not provide the 5-year warranty. The technician properly cleaned the underbody and removed the rust and then applied the coating. So I think better to go for underbody when it is still not rusted if you want 5-year warranty on same. 3M does not provide warranty if underbody is already rusted.

Hello Sir,

I have 5 years used Maruti Suzuki Ciaz. I want to do underbody coating for my car.

I have seen your video on YouTube regarding the same. I stay in Pune, Maharashtra. Where I have good underbody coating in my city? Any recommendations?
I saw in market, they are directly applying Anti Rust paint, without removing existing rust particles. They told me that, no need to remove existing rust, this anti rust material will take care of that.

Thank you.

As the blog suggest there is no harm of having a extra Coating on the car underbody. Well there was a good point mentioned in the blog that "It rather involves slight complex task - been the Under Body needs to be Scrubbed, Cleaned, Degreased before applying Anti Rust Coating" in that case most (95%) the Service station don't care about scrubbing and Degreasing the Underbody . They spray a Black colour liquid on the underbody which we as the End user never know what Chemical is that...

But if company like 3M is giving you a 5 year Warranty then you should surely Go for it ...

Someone suggested me Under body coating. I was little skeptical as to why this should be done when my vehicle is little less than 2yrs. I'd now probably go for Anti rust coating during 4th year as I stay in Hyd where car hardly comes in contact with water under the body. Saved 4K.
