What is Rust Converter, and How Does Rust Converter Work?

Most of you might have the common question- what is a rust converter, and how does it work in treating the rust on the metal frame of the trucks? As common as it may sound, there are certain things that normal people like us do not know about the rusting process and the working process of the rust removers.

Rust in metals is caused by some definitive instances like moisture in the air, being overly exposed to harsh weather conditions, etc. So, what exactly does a rust converter do? The rust converters remove the rust from the metal and prevent it from getting rusted frequently! Let us indulge in the working process of a rust converter.

When the metal surface is exposed to an adverse weather condition that is full of oxygen and water, it undergoes oxidation. When ignored for long, the metal surface becomes crumbled, and rust is formed over it, leading to corrosion.

Now, the next question arises; how does rust converter work on these corroded metal surfaces? The rust converters have a chemical substance that reacts with the rusted portion and then converts it into a black paintable surface.

It also stops further air oxidation into the surface, which prevents further rusting. Nevertheless, it would be best if you kept using the rust removers/convertors frequently to get an effective coating on the metal surface and prevent rusting again. So, now you know how does rust converter work on truck frames!

What is the Difference Between Rust Remover and Rust Converter?

If you have been following the article properly till now, you might have noticed two words for depicting the same product- rust remover and rust converter! These two might sound similar, but there is a difference between rust remover and rust converter.

As is evident by the name, the rust remover product removes the rusting from the truck frame, but the rust converter spray converts the rust on truck frames to a black paintable surface. Apart from this fundamental difference, there are a few other differences which we shall discuss next. Keep reading…

Cleaning Procedure

The rust removers work on a cleaning process by removing rust from truck frame entirely and making it a new-like surface again. In contrast, when you opt for a rust converter, you can’t just expect the conversion of the rusted layer to a black paintable surface without providing a new-like shine to the metal surface.

Elements Present

The chemical composition of both is different. The best rust converter for truck frame is made with organic polymer and tannic acid that converts reddish iron oxide into ferric tannate, which is bluish-black in color.

On the other hand, the rust removers have oxalic acid and oil-based primer as the main chemical compounds that react with the rust and make it weak, thus helping in its complete removal. Also, the converters come in liquid form, while the removers come in spray form.


One of the primary differences while choosing a rust converter or rust remover is the amount you pay for them. While the former is usually a bit pricey, you can get the remover at quite a minimal rate than the converter.

Time Consumption

Treating and preventing rust on truck frames is a time-consuming process, and when it comes to differentiating between a remover and a convertor, you must know which one takes more time to do so.

While a rust converter may take about 15-20 minutes to ready the surface for painting, a remover can take 1-3 hours for the same. On the contrary, the remover speeds up the cleaning process, which is not the case with the transformer.

How Long Does It Take for a Rust Converter to Work?

As mentioned previously in the article, a rust converter takes less time to dry as compared to a rust remover. However, you might still have the question- how long does rust converter take to work? Well, usually, a rust converter dries faster, and you can get a ‘ready to use’ surface within just 15-20 minutes.

But it is advised that you do not jump to painting or working upon the metal surface soon after it gets dried as it may not reveal the best result or outcome. So, even though you use the best rust converter for a truck frame, you must wait for at least 24 hours before starting to work on the paint again!

If needed, you can also apply another oil-based top coating, and you shall then wait for another 48 hours before the surface is ready to use.

As soon as it gets dried within 15 to 20 minutes, it may look ready for painting, but the metal surface reveals the best result only when it sits for a longer period.

Sometimes preventing rust on truck frames becomes more mandatory than treating it once because you may not always afford frequent comebacks of the rusting. So, allowing ample time to dry and then applying the paint coating will only enhance the shelf life of the rust converter on the metal surface.

And if you intend to paint the surface, do it soon after the rust converter gets dried as it may take only 15-20 minutes to get dried; painting it soon after may not bring out desired results as mentioned in the above section.

Therefore, the best rust treatment for truck frame is to apply a rust converter (two coats if needed), let it dry for a good 24 hours, use epoxy or oil-based paints to paint the metal surface, let it dry for another 48 hours, and you are done!
