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.

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.

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.


There are a lot of options when it comes to choosing the right rust prevention product.

When making your decision, take a look over all of the pros and cons of our 10 chosen best products. Also think about how well each one will be fit for your project, how much you will need, and how safe the product is.

Knowing all of that, you should be on your way to making an informed decision over which rust prevention product is the best for you.

We hope this article has really helped you out.

Good luck on your next project!
