That old corvette standing forlornly in the garage or even that wrought iron fence or the main gate that looks terrible and badly rusted requires a lot of work till they can appear shipshape. However, with the right preparation and rust converter and primer, it can quickly restore many, if not most, rusty metal surfaces to an almost new condition.

Here, the first step would be to effectively clean off all loose rust and flaking paint and then apply a rust converter. However, before you go right ahead and decide to use a rust inhibitive primer, you must know the answer to the question ‘can you prime over rust convertor?’

After all, once you know the answer to Can You Prime Over Rust Converter, you will also realize that you do not need to get down to the wholly bare and shiny metal, per se. On the contrary, you should clean off the flakes and the powdery surface rust that can help prevent the paint from adhering to the compound. However, it is pertinent to note that badly rusted metal areas will almost inevitably need a lot more prep work and quite possibly a rust converter to ensure that the final coating does not peel off.

Just what exactly is a rust converter anyway?

It is essential to have at least a practical working knowledge of exactly what an actual rust converter can do, especially concerning fighting off the various patches on the metal directly caused by rust and corrosion on hard metallic surfaces.

By and large, your average ‘rust converter’ is a more or less highly synthetic polymeric formula that converts various existing rust patches into a mostly moisture-free and matt black protective coating. One of the critical factors of this heavy-duty protective coating is that it actively eliminates the current rust present on the metallic surface. But at the same time, it also can essentially seal out all the residual moisture from the top layer of the metallic object that is being coated or covered. To answer the question ‘can you prime over rust converter,’ it is essential to understand that using such a protective covering can prevent rust formation in the future.

So, to understand if you can prime over rust converter, you have to realize that many. If not, most metallic areas are often highly protected, with not just the rust converter per se, but also the primer as well, along with any. Otherwise, high-quality oil-based paint will safely and securely resist the debilitating effects of even adverse weather conditions such as inclement weather, sunlight, rain. And people who live near the sea; even the rust is creating properties products of salt spray.

In other words, they will neither peel nor crack for an extended period. Or even as long as the oil-based paint that is the final outer covering of the painted object is manage as per paint maker’s recommendations. That is why to be able to answer the question ‘can you prime over rust converter. It is essential to realize that most of the more common rust converter forms can also quite quickly provide a superb ‘standalone’ base primer for the myriad different epoxy and even oil-based paints. It is effortless to use, and handy product is now widely touted by many industry pundits and some of the leading experts in rust corrosion protection.

When it comes to answering the question ‘can you prime over rust converter,’ it is essential to start with adequate preparations on the rust-covered surface itself. You can quickly start with a straight wire brush. If the area is already quite heavily rusted and pitted and you feel that wire brushing by hand is relatively ineffective, then you can forgo the meeting and use a drill with a wire wheel attachment for best results. After that, you can figure out if you can prime over rust convertor or use it instead of a primer such as the kind used generally for most such applications.

For various spots that are already very severely corroded and rusted or, for that matter, are a bit too delicate or even if they require a more detailed effort to clean thoroughly. It would help if you used a rust converter that will be able to soak deeps into the rust and then proceed to change the same into an almost entirely non-rusting and paintable surface. Once you have the answer to the question of can you prime over rust convertor, you can methodically and efficiently commence applying the rust convertor to the rusty surface to prepare it for a final coat of oil-based paint. Alternatively, you can even use the rust convertor’s black color coating itself as an impromptu end coat that would easily be able to outlast many seasons even when being exposed to the external environment for extended periods.

The overall lifespan of a rust converter

When it comes to answering the question, ‘can you prime over rust converter? It is essential indeed to be in a position to understand that just about all kinds of different rust removers. Yes, that also includes sprayable rust converter and paint on (with either a roller or a hand wielded paintbrush). It must generally use the verities within approximately an estimated 270 days or so from their original purchase date. And yes, it is also important to realize that this standard shelf life applies even to all those rust converter cans that have not even opened, as yet.

As a general rule, a can of rust convertor is usually available in one-gallon cans. A full gallon can easily cover about 500 feet or just about any non-porous and otherwise smooth surface.

However, it is pertinent to note here that this approximation only applies to oil-based ‘paint on’ rust removers of the sort you might be interested in using when you want to know the answer to the question of if “you can prime over rust converter”?

However, when it comes to the more ‘sprayable’ variety of the rust converter, it is estimated that a single can might be able to cover will cover approximately 300 sq. feet of the total surface area of the metal with one gallon of the product. Simultaneously, the most commonly available spray-on rust converters’ size is the right to cover around 24 square feet of metallic surfaces.  However, before trying to answer the question of whether you can prime over rust convertors on porous irregular or even textured surfaces, it is essential to note that such characters might require a far larger number of coats. You might have thought you would need before actually purchasing the product for the very first time.

The usefulness of rust convertor in preventing corrosion

Here, it is essential to understand that metal structures such as cars, gates, tanks, machinery, and trucks, and even different types of farm equipment can safely and securely coat with a rust converter. That is because this product can work on any rusty iron or even steel objects. However, the rust convertor does not work well with stoves, since it cannot handle the high temperatures that the intense heat would generate, and such high temperatures can quickly melt the whole coating completely.

Furthermore, another point that should always discuss is that when you decide if you can prime over rust convertor, it must on no account apply to any non-rusty surface. Instead, it should only try and cover up the rusted areas, per se since the very name of the product ‘rust convertor’ implies that it can convert rust. Ergo it will not work if there no rust to begin. (In case the metal is rust and corrosion free and completely shiny, it would be a lot better idea to use an ordinary ‘run of the mill’ primer and oil-based paint combination.)

However, once you have figured out that, you will need to apply the same to the rusty surface if you can prime over rust convertor. Once the body is cover entirely with a thin film or coating, it should appropriately wipe the excess product from the surface with a spotless. And damp cloth to effectively remove all of the extra rust converters before deciding if you can prime over rust converter.

There is a lot of logic behind this reasoning. In other words, should anyone apply any oil-based paint over the rust converter, then the latter will quickly glaze coat the non-rusted areas of the surface that painted and that in turn will mean that the oil paint topcoat will not be able to properly stick or adhere to those surface areas on which it applied freely.

 It is also quite possible to use a good rust converter when you are in the process of actually deciding if you can prime over rust convertor, especially regarding the ceiling or the inner walls of a tank.

But here it is essential to mention that this is only possible if you intend to use it purely as a form of primer only, and the rust convertor is being used only to cover the rusted parts alone. Apart from the above, only that specific type of (oil-based) paint should use that is entirely suitable to protect the different walls of the tank from its contents. In addition to such tanks, we can also use the erstwhile rust converter on different types of galvanized steel as long as there is a certain amount of rust on the steel object’s surface.

Using the rust convertor itself as a primer

Of course, it is unnecessary to use a coat of paint on top of the rust cover because it provides a rugged-looking all-black coating of its own. Nevertheless, it evaluated that almost regarded as desirable that one should still apply at least one coat of high-quality oil-based paint. That is even more important if the object painted will be exposed to the external environment all the time. That is, it will have to store in an outdoor location.

Using a rust converter as a primer will ensure that the final color will be almost impervious to rust and corrosion, even in a damp and salty environment. This way, the metallic object, such as a vehicle or even a yacht, will retain its original coloring for an extended period compared to surfaces that have only been primed and painted without using a rust converter.
