Well I just picked up a 2012 Wrangler Sahara today from Peel Chrysler. Loving everything about it so far over my soon-to-be-for-sale Dodge Magnum.

I got the whole song and dance at the dealer about the dealer rust proofing and decided to decline due to the high cost and everything I've read about it (including info on the APA website), which does not recommend it.

I searched the topic and found a few threads, but from what I've read I'm still a little uncertain on my options or whether rust proofing is necessary at all.

I live in the Toronto (the beach(es) to be exact) and spend some time in Montreal (visiting family) every winter. As such, I think it'll have a decent amount of salt exposure. Wondering if anyone here can help answer a few questions based on their experience or knowledge on the topic:

1) Is rust proofing really necessary? I'm financing the Wrangler and I intend to keep it for many years, so it'd be nice to make sure it'll stay looking great.
2) What kind of rustproofing is the best? i.e., undercoating spray, penetrating oil with drilling and yearly application, etc.
3) Finally, if it's necessary, where should I get it done? Krown vs Rust Check vs Crappy Tire, etc? (I'd highly appreciate if anyone can recommend exact locations in the GTA that they've had success with).

 

Krown is great stuff, and is what i would recommend, i've got a Mustang GT that will get Krowned as soon as possible, even though it wont see the road salt directly, i live near the bay and salt in the air around me, and vehicles rust out like crazy around here...

Krown is a great product, it'll make it easier for someone to work on the vehicle later on down the road since, for the most part, all hardware will be in like new condition preventing things from being seized up, the stuff is also good for the electrical connectors to prevent them from corroding up...

Im not sure about canadian tire, but i know Krown makes you take a training every year on how to spray newer vehicles and keeps their people updated on their products... thats not bad either...

as far as being in the Toronto area its a hit and miss as far as rust proofing the vehicle, if you see alot of winter miles even one application will be worth while, It'll get in all the hard to reach areas, which is where salt would likely get trapped and end up rusting it out... getting it resprayed is just preventive maintenance... krown does a full spray down of the vehicle before spraying their stuff... cant go wrong with doing that once in a while...

 

Whatever you get get it sprayed on the inside of the frame also..... they rot from the inside out also........

 

The bolt on electronic units are pretty decent as well... A higher up front cost... But work well if you install right off the hop!

 

didn't mythbusters prove those wrong? lol

thanks for the advice guys! I'll probably go with krown. I notice they're a vendor on the site. Do we get any kind of discount?

 

hey this is a post i had posted for someone on another forum. i just copied and pasted. dont mind the tone it was not intended for this post. i just dont want to re type im bad at it lol.

Most dealerships here will offer and install the electronic rust proof. Or under carriage spray if wanted. All the work gets sub contracted out like most things you add to your vehicle when buying new from dealer. For instance, if you want tinted windows upon delivery chances are they had a local company do it at a fraction of the price you paid the dealer at time of purchase.

I added mine in the Mazda afterwards. Cost me 270 dollars installed myself. Hook one wire to battery and a sticky pad sticks to your frame. And theoretically reverses the polarity in the metal. If something is metal and touching metal it conducts the electric pulse through it.

I can't remember what brand it was. I currently use the "counteract" product sold at a local auto parts store. Sells for $200 for suv version.

It is impossible to protect anything from rust. As soon as the car is built it starts the oxidation of metal mixed with air and moisture. The manufacturer would have to have metal treated by supplier prior to the commencement of the vehicle manafacturing process. And that would be really expensive. Such options may be available when purchasing high end cars with high end prices. They tried with the dolorian and failed. Making it out of stainless.

It is inevitable. You can delay with spray, paint, regular washing and products like I mentioned above. But will never stop it. I am really particular when it comes to my vehicles. It's almost like an obsession. I take pride in what is most likely the second biggest investment we make in our lives. But I also realize that unless I park my vehicle in a heated garage and it never sees snow, rain or high humidity days it's going to rust.


One other theory is that no rust protection is best. Some believe that no spray or intervention is best and gives the under carriage a chance to dry and evaporate any moisture instead of trapping it.

My best advice is to wash it frequently. Rust proof with oil based products and enjoy the vehicle. Wax it at least 4 times a year. In winter and summer. Helps protects against UV, acid rain, bird droppings, industrial air particles and bugs.

I went and spoke to the guys @ National 4X4 here in Calgary and they told me about this product. I then went on-line and did some research on it and was amazed with what it can do.

I did my complete frame (all sides) and some other chassis parts including a newly build rear bumper with 1 small can. It canbe sprayed on but I elected to use a brush as I dont have the means to spray in my garage.

Long story short I would highly recomend looking into it, its pricy but well worth it.
