    Best product to date. I have been using this product since 2019. Find it does a lot better job in preventing rust and stopping current rust. All 4 vehicles are sprayed yearly with this. Look better after I inspect it every year compared to that another product

    I have been using this stuff for years, do yourself a favour and make the switch. I used many other products for rust protection, and this is by far my favourite with the best results so far.. NO RUST.

  24. David N. (verified owner)

    This is absolutely the best product on the market for under coating rust prevention on vehicles in the northeast it dries to a waxy film. It doesn’t wipe off and prevents water penetration. I had bought brand new 2016 ram 25000. While it was still factory fresh I coated the Entire undercarriage with this product. Only now in 2023 am I now refreshing it with a second coat so I can probably leave it for another year or two.

    We have done undercoating with other products but they swelled rubber door seals and didn’t penetrate the lightly soiled frames that comes from previous undercoat jobs.
    Corrosion Free applied easy in colder conditions, less overspray, less mist in the air, penetrated the dusty layer from previous jobs and with a reasonable amount of product, especially after applying in a cooler shop, cold vehicle, and using a little more air pressure than recommended for the unfavourable shop conditions.
    So far, my assessment is that it’s a good product, time will tell the story on the door seals and the creeping spreading ability of the product.

    Great product, been searching for years for a product that WORKS. Yes its true that the product may need warming before application, also note that the correct applicator gun and orfice sizing are critical to a successful application. I Considered making my own “recipe”, but i am super happy to see that i can purchase a good tried tested and true product. If in doubt, read the Canadian armies research on this product. To me their findings say alot, with the rigorous testing they put it through. This product has basically “held” the rust on my 19yr old 1/2 ton truck. If in doubt purchase a small tester aerosol can and spray it on a vertical surface and watch it “climb and cling” to the metal.

    Fantastic product. I purchased the professional gun with attachments and have sprayed about 10 cars including my own. Well worth the extra cost if you are regularily spraying your cars.

    I had an issue with the attachments leaking at the coupling after the first year. The customer service was excellent and they sent replacement parts in a timely manner at no charge to me, fixed the problem completely.

    It seems the formulation was thinned slightly the past year as it is now easier to spray in cooler temps. I would keep the container out in the sun on inside on a heater vent prior to spraying. Use a higher psi (90 or so) if it is cooler outside.

    This stuff is virtually drip free, and will make rusted components look much better. It won’t necessarily remove existing rust but when it is coated it appears to be much cleaner and the rust is less noticeable.

    This stuff also creeps really well and sticks an impressive amount. I used to use Krown which was also a good product, but this stuff sticks better and creeps just as well.

    I will be a long time user, and this is one of the few things that will help me keep my cars 15+ years up here is the salt belt!

    The gun and wands could be better designed and it is very expensive. Not sure it does anything other than coat the surface. I doubt it “cures” rust

      Hi Tim, we are sorry to hear you are not happy with the RP460 gun. What is your concern with the gun we are happy to help you trouble shoot? The product is thick by design and will thin naturally when it is heated.

    First time user. Had the vehicle undercarriage sprayed at Canadian Tire and proceeded to do detailed coverage like inside rocker panels, door panels, quarter panels, myself. Product sprays better if warmed. I filled the gun bottle and then placed the bottle in a hot water bath for half an hour – good results. Product sticks to vehicle components with very little dripping. My suggestion for improvement:
    I do the applying on my back on the garage floor with the vehicle up on Rhrino Ramps. Its difficult to use the wide spray tip directly on the gun in this situation as i only have about 20 inches between the car bottom and the floor. So i would be very impressed if Corrosion Free, or more particularly i suppose, Corrosion Free’s gun supplier, Lemmer, would make a wand with a wide spray tip for use with the HD gun. That way i could do the wide swath spraying in my limited 20 inches of space between the vehicle undercarriage and floor. My vehicle hasn’t been through a winter yet, so can’t comment on the effectiveness of CF as a rust preventer.

    Looks like a great product so far though!


  137. Alex (verified owner)

    I used to use ACF50 and liked it a lot. It’s almost as liquid as water and sprays (fogs) nicely with my 100$ gun. Corrosion Free is gel like…even pouring into the gun wasn’t so easy. Spraying was a problem. It sprays thick and you don’t really know if it covers anything inside. I do believe it’s a good product. Most likely though i will be brushing this on outside and spraying amth else to inside panels.

    I have been using One form or another of rust proofing for at least 30 years and I for many years I have stuck with fluid film because it was doing a great job however I am blown away with all of the benefits that has come from using corrosion free and the biggest factor is it is much cleaner yet creeps and protects just as good or even better than all the rest. I switched to using it a couple years ago on my 23 year old Cherokee that is my daily driver and most people think it looks one year old so I am glad to have found corrosion free and it is light years ahead of everything else that I have been using

    I live in Southern Ontario and have been using your product for 3 years. I will say it is by far the best automotive corrosion prevention product I have used. Easy to apply, penetrates nicely into tight spots, no dripping and lasts. I apply this product myself and find it a pleasure to work with. I always apply to my van and car in early October while it is still warm outside. We pay a significant amount of money for our vehicles and it’s nice to know I am well protected from corrosion that our salty Ontario roads deliver each winter. The underside of my 2017 Chevrolet Express 3500 4×4 van looks new. What a wonderful product and I love the fact that you are a Canadian Company.”

    Saved a tonne and made sure the job was done right! Last time a company sprayed, it went on super thin and had to point out 12 spots plus that he missed…? One 4 Litre bottle was good to soak my mini van and large sedan. $65/bottle vs. $320 for both vehicles…Just bought a $58 spray gun at Princess Auto to go along with my small compressor. Sprayed at 90psi. Now, $65/yr to spray both annually, properly.

      Thanks for your review David! Our product is by design more of a gel-like consistency. If you need to make it thinner, it will naturally thin when heated. The warmer it is, the thinner it will be. Hope this helps. Take care!

    My first attempt to spray the product on my car was not really a success. I put too much product because of my lack of experience. I did my son’s car after that and was very pleased to catch up how to play with the trigger to mix air and product property. The video said pull first stage for air and second stage for product. This is aft truth. To spray the product you need to push the second stage only by pulse to get the product in the line and use the air to spray the product. Finally the product is awesome when you get the trick. Thanks

    Works well. I have a 2017 Ford F-150 that I used this product on twice so far. I put it in and on the frame heavy and covered the complete undercarriage and truck looks like it just came from the showroom after 2 New England winters. Even the driveshaft, which is raw steel shows no signs of aging. I have used Fluid Film prior to finding this product and would never go back. This product is odorless and doesn’t swell non oil resistant rubber as Fluid Film does. Great product, highly recommended

    This is my third year ordering from CorrosionFree. In my opinion this is a great product. I did a test spray on some scrap metal at home. It covered well with very little drip. The oil continued to creep into untreated crevices and seams over the next several days. Saw the same result on my pickup truck. Love this product and the shipper. My order was confirmed immediately and shipped by the next day. I highly recommend this company.

    For me, the biggest measuring stick for any company is customer support. This company so far not only deals with high quality products but their customer service is fantastic. They answered all my questions in a clear and concise manner and usually in a couple of hours. Shipping is fast and I have had no more than 2 days “flash to bang”. A pleasure to have a company that takes pride in their products and treats customers like their actually important!

    Had this treatment done professionally in New pickup last year. Very impressed. Bought 5 gallons and a gun to do my commercial vehicles now, great nothing but great things from people who have used this and so far I agree completely!

    Iv’e been using Corrosion for several years and i would say it’s one of the best products on the market. It’s drip free ,and very easy to apply . My cars are aging very well one of them is 10 years old and showing no signs of corrosion anywhere, the other is 12 years old still amazing condition. If you really care about your car buy the self starter kit it’s a little expensive but certainly worth it . Buy with confidence it really does work .

    Outstanding product. Works great. I have recommended it to a number of my friends, and everybody is very happy with it. I used it to treat my Mitsubishi Outlander 2009. It is very interesting how the product interacts with existing rust. From outside, it looks like the existing rust got more “flaky”; it falls of easier; it looks like the product kind of dried off on the rusty areas. In fact, it looks like it goes through it down to the unaffected metal actually lifting the “flaky” rust. So, the second spray at the rusty areas is highly recommended.

    Here are one-year-after-the-treatment photos, be your own judge:

    Outstanding ! Nothing else to say

    I have used this product since 2001.It is the best product on the market in my opinion. I have a 2001 pt cruiser i bought new,this car is still like the day i bought it and it is totally rust free because of this product, I have been disappointed with other products that claim to stop rust, Rust Cure Formula 3000 Stops Rust.

    I used the product last year on my dodge truck. So far so good. No rust anywhere. The truck is a 2003 and last winter was the first one that it spent in Ohio. It is a bit messy, but sticks to the metal. I noticed fewer squeeks as bushings and connections are lubricated by the product. I plan on applying on my vehicles every fall.

    I have used this product for 2 years now and have had good results. I like the fact that it doesn’t harm rubber components so I don’t have to worry about overspray. I bought the cheaper spray gun and it does work well with this product. Price is a little high so I rated it at 4 stars.

  212. Christopher

    Fast Shipping and communication was great with the company. Answered every question i had!

    Application of the product is easy enough. I had to buy cheaper third-party undercoating gun with extension wands to apply it. It can be messy at times but it does cling to the metal. It does bubble when it is first applied but i’m not sure it is really “eating” the rust away. I thinkit is merely the mix of air in the product that is escaping- both with the undercoating gun and with the spray can (Yes i used the spray can on my garage door hinges and bearings)

    It does “drip” a bit- more like trickle at the door seams because i flooded the whole panel which is normal in this case. But it does not drip as other products do and i don’t see any of the product on my garage floor.

    Another big plus- NO FUNNY SMELL unlike the other products. Well it does not smell at all!!

    Overall, i’m really happy with the product itself – time will tell how it holds the rust away. And i’m really happy with the customer service experience. Oh, i got some free samples of the stain remover also. Haven’t used it yet but i will.

    On another note, what the other reviewer said about your entry gun makes sense- why don’t you provide the wands for your cheaper spray gun? Not everyone can (or want to) afford the price for the Deluxe gun. Plus, if indeed your product will hold for 18 months as claimed, we will not be using the deluxe gun as often to justify the purchase.

    I can understand that you will want us to go for the deluxe gun if we want the wands but there is a huge price difference. The undercoating gun (with wands) i purchased cost me 70$ (Tax incl.). I would have gladly spent it with your company provided you had the product.

    Product has no smell and goes on thick or thin depending on how you have your Deluxe HD RP460 Applicator Gun with Wands setup. Good idea to apply in temperatures above 10 C as the product is difficult to get out of the bottle. When the bottle is empty, much product is wasted if you don’t cut the bottle and scoop out the remainder by hand.

    Haven’t used it for long, so I don’t really know if it stops or eliminates rust. I can say that it goes on and stays on. I applied a 1G jug coat on a motorhome a year ago and I’m happy to say not much has washed away. This year, I applied another 1G jug most everywhere else I missed the first time. Seems the more I apply, the more I want to apply. I usually go around 3 times; each time finding spots I’ve missed. Time will tell…

    Great product works amazingly, We use this to protect our fleet of delivery trucks in Toronto Canada so we know about road salts and rust ! It’s easy to apply but it does make a mess….wear some old clothes !

  215. charles

    I have no doubt this stuff sticks quite awhile. I really do enjoy how thick it is. Though I have not really seen too much effect on the rust itself, I have no doubt it halts any progress of the rust because of the thickness and material properties. (someone mentioned on a random forum that he saw a ton of white bubbles as it “ate” away the rust.; I can’t say I saw any immediate chemical reaction)

    As one downside seems to be it’s a bit messy when applied by a newcomer to compressed air, painting setups. ?
    I am however curious as to why you don’t supply a wand/extension set for the cheaper spray gun? I think that’s the only main thing I would say was disappointing overall.

    The extreme upside as well which I don’t see you advertise is this.
    I bought a vehicle in a crunch, it was decently rusty, EVERYWHERE. (I live in Iowa though, with constant salts on the roads in winter) I applied this stuff hoping it’ll help the frame last a few more years, heck, if I keep it covered maybe even more. The one beneficial oddity I found after applying the Rust Cure, was the amazing ride quality the vehicle has now. No kidding. And after thinking about it, it would make sense that an old rusty car would have a bit of a stiffer frame as it’s progressed with age. But now it feels almost like a new vehicle as I can only imagine bushings were rehydrated/conditioned, joints get an extra bit of lubricant to help mechanical movement (the steering feels a bit better too), and leaf springs actually have movement as before I would bet it was pretty tough to move, rust grinding on rust.

    Anyways, just wanted to say there’s a selling point as well. I’m really impressed though!

      Hello Charles, thank you for your review and your feedback. We appreciate it! The standard gun is not designed to accept wands. It is a free spray gun designed for large surfaces like vehicle bottoms, farm equipment, heavy machinery etc. The Deluxe Gun is designed to atomize the product, mixing the product with air to form a fog. It is a professional grade gun that will last many, many years of use. We understand it is not in the budget of all customers so we do have aerosol cans with plastic tube attachment that does help get into those hard to reach areas. We are pleased to hear your vehicle has now had a rust protection treatment and is well lubricated! Thank you for order and review.
