1 Corroseal Water-Based Rust Converter Metal Primer
Starting us out, we have the Corroseal Water-Based Rust Converter Metal Primer. Its best qualities are pretty much given to you in the title. But let’s go over these in more detail.
The fact that this product is water-based means that it is easy to clean up. All you have to do is use soap and water, and you’ll have the mess all gone in no time! And it’s perfectly safe to clean up. What makes it so safe, you might be wondering?
Not only is this rust prevention product water-based, but it is also non-flammable and non-corrosive, making it extra safe. But enough about safety and clean-up. Let’s get down to the really important stuff here.
Corroseal will solve all of your rust problems. Just applying this to nearly any metal area will not only prevent future rust but eliminate any pre-existing rust. But that’s not all.
This product also serves as a paint, primer, and rust converter all in one! So you won’t need to buy multiple products to get the job done. And, it’s super easy to apply! Just brush, roll, or spray it on. We’ll leave that up to you to decide the easiest way of application that is preferable to you.
Corroseal is perfect for all your automotive needs, but it also works just as well for marine, general household, and industrial applications. So if you have any other projects in any of these areas, this rust prevention product has you completely covered.
Whatever you use this product on, you’ll have that metal surface looking as good as new once again!
2 BOESHIELD T-9 Rust & Corrosion Protection/Inhibitor And Waterproof Lubrication
While this product was originally made for aircraft, don’t let that fool you into believing that that is the only thing this works well on. This product also works wonderfully on all things automotive, household, marine, and more. And, it does more than just eliminate and prevent future rust.
Boeshield T-9 also provides a waterproof exterior to whatever you apply it to. How, you ask? When it dries, it leaves a waxy paraffin coating that gets rid of moisture and minor corrosion.
And, it does this without the risk of harm! That’s right, Boeshield T-9 provides rust prevention and waterproof lubrication without the use of dangerous chemicals or products such as Teflon, silicone, fluorocarbons, MEK, or acetone.
It is also safe to use on other paints, all metal surfaces, and even plastic and vinyl. You can even use it on electronics – it’s that safe.
If you use this product on places that have had other products used on it before, there is no need to worry. Boeshield T-9 works to remove dirt and foreign materials so that there is nothing in the way. Then, it can penetrate deeply for a longer lasting wax finish.
3 3M 03584 Professional Grade Rubberized Undercoating
If you are looking for something simple that will give your vehicle the extra protection it needs in order to last a long time, this is your kind of product. Unlike a lot of other rust preventatives, this one is specially designed just for vehicles.
When a product is made for a specific use, you know that it’s guaranteed to do a good job.
3M will protect your car’s underside from any corrosion, water, or salt that it is exposed to. And, it will look nice with a black protective coating. But there is more.
Because this product is made specifically for automotive purposes, it also has another special feature. 3M will help muffle sound, giving you a quieter ride when you are on the road. This is a quality that not a lot of rust preventatives have! But how does it work, exactly?
Because this is a rubberized undercoating, it helps insulate the vehicle cabin from just about any noise. This way, you won’t have to listen to the engine revving so loudly, and you can keep outside noises, well, on the outside!
This product is great for use on vehicle undercarriages, wheel wells, fenders, quarter panels, and much more.
With all of the added protection, this product could even potentially increase your vehicle’s lifespan. After all, your vehicle is going to be exposed to a lot over the years, so it’s important to be prepared and take the extra steps in preventing rust and erosion.
4 Fluid Film FLUIAS11
There are quite a number of benefits that fit into this 11.75 ounce can, let me tell you.
First of all, Fluid Film is more than just a rust and corrosion preventative. This product also serves as a penetrant and a lubricant, giving you the highest quality multipurpose product.
You read that right – this product serves a lot of different purposes and can be used in a variety of places. But how safe is it?
While Fluid Film is in fact very flammable, is it still non-toxic, due to the fact that it is lanolin-based. So just make sure that you are not spraying it near any open flames or heat sources, and you will be perfectly fine. It won’t hurt you otherwise, and it’s a perfectly trusted brand.
In fact, it’s been considered the best since 1943. How about that!
And with this product coming in a spray can, it is super easy to apply. Wherever you are needed rust and corrosion protection or lubrication, you just spray this directly to the area. But the best thing about Fluid Film?
It is made and manufactured all right here in the USA. That’s a hard thing to find these days, but with this product, you won’t have to look any further. So if you like to support the USA while working on your car, this is the rust prevention product you need.
5 CRC 06026 Heavy Duty Corrosion Inhibitor
CRC might be specifically designed for marine purposes, but don’t let that fool you into thinking that is the only thing that this heavy duty corrosion inhibitor is good for. Plus, you might actually want a product that you can use on both your car and your boat.
And the good news is that you can buy CRC 06026 Heavy Duty Corrosion Inhibitor in packs of 6, so you can keep some in your car garage and the rest by the boat dock. When you buy in high amounts like this, the price will come out to a lot cheaper that if you’d bought them all individually too.
CRS is guaranteed to prevent rust and corrosion for a really long time. But this isn’t the only benefit of this product.
It will also resist damage from salt spray and high humidity. If you live by the ocean or in an area that has high humidity, this is a really important feature that could save you a lot of money.
After all, you want your vehicles and boats to last as long as they possibly can. And when you use this product, it helps with that. But what exactly can you use CRS on?
Use it on various metal surfaces, electrical connections, engine components, equipment storage, fasteners, motors, and so much more. It will also protect steering and throttle linkages.
What more could you ask for? This is a great product to keep around.
6 VHT SP229 Rust Convertor Can
While there are a few different options that you can get from this brand, you can’t go wrong with getting this one in particular. The one we are talking about here is the VHT Specialty Rust Convertor that works fantastically on just about everything. But more on that a little later on.
This product destroys and eliminates rust immediately on contact. A lot of products out there are only going to cover up rust that is already there, then prevent any future rust. But not VHT.
VHT removes all rust, then, when it dries, it will prevent any and all future rusting. It sprays on clear, then dries with a solid black finish. Now, let’s talk about what this product works so well on.
You can use VHT on metal, body filler, and fiberglass. It can easily be applied just by simply spraying it on. Afterward, you will be left with a flat and smooth solid black finish that will prevent rust from forming for a very long time.
This product is specially designed for automotive use, so you’ll be left with an awesome looking paint job by the end of it all. But please take certain safety precautions when using this product.
The vapors caused by spraying the contents of the can are extremely flammable and very toxic. If not careful, it can irritate your eyes, skin, respiratory system, and even blood if absorbed through the skin.
But enough about the dangers, there are a lot of positive things about this product. And, if you really love it, you can get it in packs of 6 instead of buying a single 10.25-ounce can.
7 POR-15 45404 Rust Preventive Coating
POR-15 is just what you need if you are looking for a permanent solution to preventing rust. This product goes on just like normal paint, except it seals rust permanently and prevents any future rusting from ever happening.
This product will provide you with a solid smooth black finish, all without having to remove any rust beforehand. And, it’s permanent rust protection!
There are a lot of products out there that guarantee long-lasting rust prevention, but POR-15 does more than that – it lasts forever.
This company also guarantees that they are the original and the best, and have been since 1978. Now, that’s impressive!
There is just one inconvenient feature about this product. If the area you are covering is an area that will be exposed to sunlight, you will need to put a top coat over this rust preventative coating in order to prevent damage. This product is super sensitive to UV light.
But, if the area won’t be exposed to any sunlight, you have nothing to worry about! Just be sure to use safety precautions when applying this product, as the vapors from it can cause health issues if you are not careful. Once it is dry though, you should have nothing to worry about.
POR-15 is lead-free, so once dry, it is perfectly safe. This is a great product if you are looking for excellent rust elimination and prevention. And, you have the option to buy it in either pint or quart size, depending on your needs.
8 Rust Bullet Automotive
The Rust Bullet is the first and only rust preventative to have a US patent. That in itself should say a lot about this incredible product, but that’s not all. It doesn’t have just one US patent – it has 2!
One of the patents is for the fact that this product kills rust. The other is for preventing rust from coming back.
This product is great for automotive use. Use it for preventing rust from forming on the undercarriage, frame, floor pans, rocker panels, suspension and so much more. You can use it on more areas than on your car though!
It works great for industrial, marine, home, and farm uses as well. If you prefer to keep this product in multiple areas – such as leaving a container down by the farm and another in your garage, that’s no problem.
You have a wide range of option for how you want to buy Rust Bullet. Choose between buying a 5-gallon, 1-gallon, quart, pint, or quarter-pint container. Or go even further and choose from a pack of 6 single quarts, a pack of 4 single quarts, a pack of 6 quarter-pints, or a pack of 2 quarter-pints. There are lots of packaging options.
And, it’s super easy to apply. You can use a roller, a brush, or even a spray bottle to apply Rust Bullet to the metal area.
Another great plus is that Rust Bullet is UV resistant, therefore, you’ll have no need to put a top coat on. Unless of course, you just want the added protection. But it is completely up to your preference, not this product’s quality.
You can be assured that you are getting the highest quality product when you buy the Rust Bullet for rust prevention. After all, it’s made in the USA!
Just be sure to take safety precaution when applying this product. The liquid and vapors are combustible
9 Permatex 81849 Rust Treatment
Permatex Rust Treatment will have any rusted metal surface looking brand new in a matter of minutes. That ugly, damaging orange rust will soon be replaced with a long-lasting layer of black polymer.
This product is just what you need to fix up that old car of yours, as it works great on automotive applications. It will also do well on aside from metal, such as body filler and fiberglass. In fact, it is specially formulated for these types of materials.
And, once it dries, you can easily paint over the rust treatment for any color or design that you want! Of course, you don’t have to if you don’t want to. But the option is definitely there. This product serves as a fantastic primer that will keep all rust from ever coming back.
Just make sure that the area that you are applying this product to is not going to exceed 200 degrees Fahrenheit. As long as that isn’t the case, you can be guaranteed that this rust treatment is going to last you a long time.
When you go to buy Permatex, you can choose between getting a 10.25-ounce bottle, 16-ounce bottle, or 8-ounce bottle. The 10.25-ounce bottle is a spray bottle, making the application process very easy. If this is the kind you buy, please be careful about the vapors, as these are very flammable and can be harmful.
With the other bottles, you’ll just need a brush to dip into it, and you will be good to go. You will be guaranteed long-lasting rust protection when you use this product.
10 Rust-Oleum Automotive 248659 Rust Reformer
If you have a surface that you are looking forward to painting, but it is covered in rust, then you should probably look into buying Rust-Oleum. This particular product is specially designed for automotive applications too, so it’ll work really well for fixing up that old car of yours.
No longer will you have to sand rust down in order to have rust-free metal. Just apply this product to it, and it will instantly have a rust-free, easily paintable surface for you to work with.

Best Rust Prevention Product Buyer’s Guide
Now that we have gone through the 10 best rust prevention products that are out there and available on the market, we’re going to go over a few things that will help you to make your final decision.
We know that there are a lot of options out there, and even when narrowing it down to 10, it’s still hard to choose just one! But allow us to help you by giving you a few specific questions you should ask yourself and think over.
Does It Fit The Job You’re Looking For?
The type of rust prevention product that you should buy is going to depend on the type of project that you’re working on.
If you know that you’re only going to be using rust prevention on cars, you probably won’t care much about whether or not the product is also good for household items or aircraft.
On the other hand, if you have a lot of items aside from the vehicles that need to have rust removed from them as well, you might consider getting a product that is suitable for both projects.
Ask yourself if you plan to paint over it after you take care of the rust. If so, get a rust preventative that works as a paint primer as well. Is the thing that you are rust-proofing going to be exposed to water? If so, get a product that will also waterproof it.
Some rust removing/preventing products are more simple, while others have added qualities that can really come in handy. It all depends on what your needs are.
How Much Do You Need?
The next question is how much rust prevention do you need? Some of these brands come in small aerosol cans, while others can be bought by the 5-gallon bucket.
If you know you only need to fix one spot on your car or something else, one aerosol can might be enough for you.
But if you have a big project ahead of you, or you own an auto shop, you might want to consider buying in bulk.
Only some of these brands that we have mentioned come in bulk, so that factor alone could alter your decision-making process pretty dramatically.
Is It Safe?
Finally, you have to ask yourself, is the product safe? Some rust prevention products are completely harmless and non-toxic, while others are not. They can cause damage to your eyes, skin, lungs, and more.
If you are dealing with a rust prevention product that poses these dangers, you need to be completely prepared. Make sure you are working outside where there is plenty of fresh air. Also, have an appropriate mask and gloves when working.
Many are also extremely flammable and explosive. This is okay if you know you’re not going to be around heat or flame, but if you are, you should consider a product that is in no way flammable.
Another important note to mention is that these products need to be kept out of reach from children and pets. If you have either, the safer choice would be to pick a product that is non-toxic.
