Rust Check Vs Krown

Known is a petroleum based rust inhibitor designed to slow down or inhibit corrosion on your vehicle. Crosscheck treats vehicles with a corrosion inhibitor that forms a bonded layer on the surface of the metal.

The product then acts as a barrier, preventing water and oxygen molecules to be absorbed by the metal, therefore disabling its ability to rust. The formula is designed to eliminate moisture, and is thin enough to penetrate into all the seams and crevices of your vehicle.

Due to the properties in Corrosion Free’s formula, their solution chases down and pushes away moisture, allowing it to creep into wet places you didn’t even know were there. This solution covers over the areas that are susceptible to rust with a tar based product, and can offer a visually appealing look to the underside of your new car.

It’s easy to get caught up in the interesting world of new tech features for vehicles, however the technology is still very new, and its effectiveness is met with mixed reviews from consumers. There are many things to consider when deciding which option is best for your vehicle, such as type, cost, dripping or non-dripping solutions, as well as the overall effectiveness of the product you choose.

After an extensive study testing their vehicles in the harshest conditions, Corrosion Free was the clear winner with a 90% effective rating for inhibiting rust. We tend to agree, adding that its clean and transparent application helps it preserve the “factory new” look to your vehicle.

Both Known and Crosscheck are both still considerably viable options when choosing how to rustproof your vehicle, but in terms of overall value and effectiveness, neither stacked up to Corrosion Free. When considering the best option for protecting your vehicle, choosing a solution with a great warranty will provide you with the peace of mind knowing you made the right decisions.

We recommend carefully reading through all warranties, but here’s a snapshot of what’s included for the top three rust proofing solutions: Corrosion Free is the only warranty that doesn’t require a rust -thru or hole in a panel to cover repairs.

These products don’t have the ability to penetrate into the hard-to-reach seams and crevices where rust is more likely to form. Plus, coatings have been known to crack and chip, causing moisture to trap itself against metal surfaces, accelerating the corrosion process.

Even the effectiveness top-rated solutions like Corrosion Free can be negated by poor service technicians. If you can’t find a great dealer for the product you want, it could be worth considering your second or third choice to guarantee it is applied properly and done right the first time.

Member Apr 29, 2014 970 posts 314 up votes Pickering, ON Happy early New Year everyone, I have a 1-week only Dodge Grand Caravan and was looking for rust proofing suggestions. A friend of mine works at Toyota dealership service department, and he suggested Known but it's very messy and not as effect as the other 2.

A lot of people recommend Corrosion Free but mostly Canadian Tire offers it and you don't need to be a genius not to use their auto service. Dec 30th, 2016 11:40 pm nayan97 Deal Addict Mar 4, 2011 1181 posts 546 up votes Kitchener.

Member Dec 14, 2012 593 posts 128 up votes I tried them all (and more including Heart, Cobra1, Diamond Vote, ..., to name a few)....and always go back to Known because they apply the most amount of oil and spray at more locations throughout the vehicle.

Of course, it drips, but I just see that as proof that they did a good job. If you can't stand seeing oil, then go with a permanent undercoating either through a dealer (or independent undercoated). Alternately, if cleanliness is a priority, Corrosion Free may be an option.

+1 Keep in mind the permanent rubberized coatings if it gets compromised or it starts peeling, may hold salt and moisture underneath next to the metal. In fact most people who do rustproof, do it in warmer weather for this reason.

It looks like a typical quick lube/car wash joint, but I was able to watch the work and ask for more product be sprayed in certain areas, and they were good about it.

I heard that spraying these areas with silicone, before you go to Known, can help combat the effect. Dec 31st, 2016 9:19 pm betamaxman Deal Fanatic Dec 27, 2006 5783 posts 1951 up votes Cornwall PE Julius Maximus wrote: Yes, it causes these strips to swell.

The rest of the cars weather stripping fared out ok. My 31-year-old Monte was rust checked since new, only every 5 years or so because it's stored in winter, and the weather stripping is in not too bad shape, the felt strips holding the side glass tight will need replacing soon though but that is a common thing even without undercoating.

I also like CF for its DIY capabilities and the fact that is goes on sale at TSC often at 5.00 a spray can. Member Apr 29, 2014 970 posts 314 up votes Pickering, ON jaydog4 wrote: You will have supporters of each brand.

The Canadian Army has actually commissioned several studies on the benefits of rust proofing their vehicles and equipment. My first experience with rust was when I was still a young lad, and I was standing next to my grandmother’s new-looking first generation Ford Escort hatchback that was more than a decade old.

My father carefully explained to me that the reason the car was in such good shape was because it was Rust Checked every year since it was new. That lesson stuck with me and I’ve used Crosscheck on my vehicles ever since I was a teenager in an uncharacteristic example of brand loyalty on my part.

That car drove like a dream and is the easiest shifting manual I’ve had the pleasure of driving. To my great surprise, they offered to get it professionally repaired free of charge licking split, which I later found out was because the rust was due to a known manufacturer’s defect.

The wheel well was actually completely rusted out but it was all hidden underneath the paint. That may not seem like a win for Crosscheck, but now that I was aware of the problem I saw many other 2005 Mazda 3s that had massive rust spots in several places including much bigger problems with the wheel wells, so mine was clearly rusting significantly slower even given the defect.

When I finally sold the Mazda 3 in 2013, the buyers had their mechanic inspect it, and he said it was one of the best looking 2005 vehicles he’d ever seen. There have been several tests run by the Canadian Army on which rust proofing product provides the best protection.

They found that Corrosion Free was almost 90% effective at inhibiting rust even in the harshest climates. It typically costs around $130 per year to get an oil-based rust prevention product applied, which is pretty expensive.

Known and Crosscheck have similar pricing that starts at $130 for the smallest vehicles and moves up to at least $150 for trucks. Corrosion Free doesn’t publish their prices on their website, so I called my local dealer to inquire.

This price is for the Complete Protection Package, which is definitely the one you want and the most comparable to Known and Crosscheck ’s service. It’s possible for these oil-based solutions to slightly damage the rubber seals on your vehicle, but other than that they are completely safe.

The only slightly annoying thing you’ll notice is the oily residue that’s left behind by the rust treatment. It’s particularly noticeable in the engine compartment which tends to eventually look quite black and dirty as grime clings to the oily substance over time.

When I first learned that they sometimes drill holes in cars to gain access to the inner panels for a better application, I was quite concerned. Once the application is complete, they plug the holes with small rubber stoppers to prevent the oil from leaking out and water from getting in.

If you can find a Corrosion Free dealer in your area that isn’t Canadian Tire, then that would be my recommendation, otherwise you might want to consider Known as a good-enough second bet. There are also some electricity-based products that keep a live current going through the metal in your car that is supposed to prevent rust.
