I guess it all depends on who and how it is done.
I personally do not believe it is worth the cost or the potential for damage it could cause.
I do not think that rust proofing "no rustproofing material evident" is proof that these vehicles were not done at the factory. Corrosion protection applied at the factory may not look any different than another layer of paint. An area for air to circulate and any moisture to exit is more important than spraying on "rust proofing. Also frequent washes during snow and salt periods go a long way. Touching up the underside from chips etc goes a long way in preventing rust from developing. Living in the big city for many years with roads paved in salt during the winter I have had no issues with rust on my vehicles.
Oh yes maybe the 1960's or 1970's I did have. Especially one that was rust proofed that rusted out in 3 years. But that was the quality back then along with a sloppy rust proofing job I am sure.
Just my humble opinion.

Have used Krown for 10 plus years on several vehicle and have never had an issue with rust either from inside or surface. It does drip for a few weeks in warm weather and I usually park it on an old tarp. Like several posts have mentioned wash and wax can help to prevent rust as well.

So I have to start this off with. I DO NOT WORK FOR KROWN and am not affilliated in any way.

With that out of the way. My son bought a 98 Ford Explorer. It had been protected with krown. We have no idea how many times. It is an Ontario car. it is RUST FREE. (rare thing on explorers of this era)


I have is no doubt Krown works. Whether or not our JEEPs need it is another question entirely.

I am having mine done soon.

I agree with Sangill... Rust proofing used to be a phenominal idea 15-20 years ago. Now the metal used in new cars is a much different animal. Not only is the steel less susceptible to rust, but the treatment used to treat, prepare and paint the various panels is much different.

I would add rust treating your vehicle will not void any warranty. They would have to prove that what you did somehow caused damage that lead to a warranty claim which is unlikely if not impossible to prove.

You don't need rustproofing. Manufacturers do not supply repair parts beyond 10 years of manufacture. When it biodegrades get a new vehicle. If you want it forever hermetically seal it and put it in a museum. Every vehicle I ever owned was Totaled before it rusted out.

These spray in rustproofing is for inside out rust protection. For exterior outside-in protection look for someone to install 3M Paint Protection Film. It's like window tint for your paint. You can hardly see it after applied correctly. http://solutions.3m.com/wps/portal/...Aftermarket/Our-Brands/Scotchgard-Pro-Series/

After reading this thread as a new member to the forums, I'm still trying to figure out what the consensus is for rust proofing on our Jeeps!

From the sounds of it our Jeeps are built pretty tough already and Krown's rust proofing is a good vendor to go get rust proofing done at, but at the end of the day, do our Cherokees need the additional rust proofing?

Thanks

I had a 1999 Ford Explorer which I had rustproofed by Krown. Not a spec of rust. I've used Krown for decades on all my vehicles and they all had no rust on them and they all were over 10 years old when I traded them in. The only rust problem I had was around the sunroof of a Mazda 323, since they don't spray the roof of the car. If you are planning on keeping your vehicle for a while, it is a good investment in my opinion.

I should get my factory order sometime in the summer, and I'm considering getting Krown rustproofing when I get it.

This thread was started 2.5 years ago and some owners have had their Cherokee's over 4 Canadian winters now.

Anyone have any updates on how their vehicles has aged with Krown or without?

@JonnyVee, sorry I have not checked this thread for a while.

I had mine done within weeks of taking delivery, it was in Jan 2015. I was nervous at the time about the holes they drilled but it has been fine so far as the Jeep has been krowned 3 times since then. They replaced the plastic plugs each time and my Jeep drips for a few days after each visit.

I do the perennial maintenance myself and it was nice to see the underside rust free. I saw a YouTube video made in Ontario someone replacing his front brakes, could not help but notice some rust had started on that job.

You can review this multi-part YouTube video by Eric O on Krown Rust Proofing, it should answer many of our quesitons:

When I was buying my used 2015 TH, I asked the dealer about having it rust-protected. The vehicle was sold to the original owner with corrosion and rust protection and the dealer told me not to take it to Crown as it could void the warranties I already had in place which run for something like another 30 years (2049). I doubt I'll still have it in 30 years.

 

[Jeepster1]

Modern day vehicles like the Cherokee do not need to be rust proofed etc.
The danger is the Cherokee has many drain holes built into the vehicle and if you accidently plug some up problems will follow. Water has to drain or it will sit and cause eventual corrosion over time. It can also freeze if trapped and cause damage.

There is a u-tube video on the production process for the Cherokee which includes the bath it goes into for corrosion protection.

The best protection you can give your vehicle is a regular wash as much as possible during the winter to get that corrosive salt off the vehicle, especially the underside. Most washes have an underside wash available. I go as slow as possible through that part.
But again its a personal choice to have it done.

 

[UN4GTBL]

I never rust-proofed my Caliber, and it's 11 years old now. The only areas I'll really fuss over are the bottoms of the doors (these are problems in general for vehicles), and the "dog leg" section just in front of the rear wheels (my Caliber has signs of early decay there).

 

[greaserman]

I had my old chevy s10 for 18 years

Had it known sprayed ever year for 15 years and not a spec of rust on it.

In the last 3 years of not spraying rust started to show up.

I will be taking my 2018 cherokee in September for krown.

My van was Krowned. I looked underneath when I got home, it was dry. Took it back, they said it must have dried up. Bad shop did crap work on an old van. Other Krown in town sprayed my other van a little better, they probably do more thorough job on newer vans but my gas filler rusted out next year, not a spec of oil anywhere above tank, just what they saw underneath.

You can buy genuine Krowm from Krown, 250 bucks for 20 liters. Sprayer from princess auto is 40 bucks. I can get 6 cars from a pail. I will do my jeep myself.

Krown sprays the oil hot so it is thin. They probably use less than a liter per car. My way everything looks greasy, and doors creep oil for months. If it creeps out you know it creeps up too.

Krown will wash underneath, then spray over water. I dont trust that at all, oil will seal in moisture.

When I got my 2018 Cherokee, the Ford dealership I got it from brainwashed me into an expensive electric Rust Detector unit. Is it total BS?

 

[sanghill]

I think BS. I did the same thing decades ago on my SAAB I think.
I installed the electrical device and the wires to the end things.
It was supposed to reverse the electrical current flow in the body.
As far as I could tell it didn't work.
I even tried the anode plug used in a hot water heater, that didn't work.
The only thing that works is wash all of the salt off every time you drive in salt. Then thoroughly dry the entire car.
A guy I new in salt country built a heated pole barn where he could wash and dry his vehicles.
The only other thing that works is have a Summer vehicle and a Winter vehicle.
