What you should know before buying header paints

The header is part of the exhaust system and is subjected to high temperatures as the engine goes about its job. Typically, the headers are just bare metal, which is why it is common to see them in rust color. When talking about painting them, it is not just about header paint colors; the exhaust header paint needed would have to withstand high temperatures and provide good surface coating and protection. With headers, paint is never just about aesthetics and color. With this, we took the time to research just what is essential when choosing the best exhaust paint available now. Take a look at them below.

Heat Resistance

Typically, headers reach temperatures of 500 degrees Fahrenheit on average, so part of how to paint headers would be considering how much heat the paint can handle. After all, the combustion engine is basically just housing for a controlled explosion, so there is a lot of heat generated. Regular paint will just end up being burned off the header’s surface, and therefore a specially formulated paint such as high temp spray paint for exhaust is needed.

Heat resistance is the one consideration and factor that you cannot skip when choosing what to paint your vehicle’s exhaust system. Ideally, get the best exhaust manifold paint that can withstand temperatures of up to 15 degrees Fahrenheit. For us, this would put your choice safely above this parameter. Always choose those paints that have a high temp header paint label on them.

Ease of application

Usually, a can of spray paint is simply pointed, and the nozzle pressed in the direction you want to be painted. With specialty spray-on paints, it can be a little bit more complicated than that. As an example, in a vht header paint review, this product needs to be sprayed on in opposing directions to achieve its effect. This is contrasted by the rustoleum header paint, which you simply spray on and leave to dry. Each product would have a different way of application.

Another way is to buy paint by the can instead of a spray can and use an air compressor to paint your headers. This would be the route to take if you operate professionally or need to paint several manifolds with high temp exhaust paint. In addition, you also have the ability to mix and match header paint colors with ease with this method. However, this needs expensive equipment, as well as a significant space to use them. If you are just learning how to paint headers, the header spray paint in a can would be the easiest way to apply. In terms of ease of application, ready-mix spray-on engine header paint such as the duplicolor header paint is the way to go.

Quality

The quality of the best header paint should always be top-tier; otherwise, it would not stay long in the market. When choosing, keep on the lookout for great articles that provide guides and even reviews, such as the vht flameproof review, among others. Making the mistake of getting a lower-quality manifold paint can cost you expenses along the way. For one, these lower quality paint will not have adequate protection against rust and the elements and can actually speed up corrosion instead of preventing it.

One kind of header paint that stands out from the rest is the emergence of ceramic coating paint for headers and is a relatively new formulation. These kinds belong in the higher-end category of exhaust paint colors, and ceramic header paint is always high quality. Always choose the higher quality product for your peace of mind.

Rust resistance

Rust is a major enemy of car owners, and rust on the manifold or headers is never good. Therefore always choose a hi temp exhaust paint that also has additional rust-proofing properties. Remember that the best header coating will always have this feature on their product. Along with rust inhibition characteristics, the header paint that you choose should also have oil and water resistance. Bear these in mind when choosing what is the best header paint.
Chipping
Along with its chemical protection, the best header paints also exhibit physical protection of the header surface from the elements, especially small debris. Lower quality paint can be prone to chipping and flaking. In reviews, like in the vht vs rustoleum high heat review and comparison, both of these brands exhibit high resistance to chipping. Keep in mind that headers and manifolds can be exposed to dirt and debris while on the road. With this in mind, any coating you put in there should be able to handle these.

Advantages of using header paint

There is an inherent advantage when you use tools and equipment specific for that particular job and it is the same with paint. If you have knowledge on how to coat headers, then you would know just about how useless it would be to use ordinary paint on headers. Using ceramic header paint or knowing how to paint headers with vht are just two things that add up to the effectivity of header paints. Below are some of their characteristics that illustrate their advantage over standard paint.

Increase heat tolerance

The engine bay, where the manifold and headers are located, is a hot place. Exactly how hot, you ask? Some engine bays can generate up to 1000 degrees Fahrenheit, which is more than enough to burn off standard paint on any of its parts. While headers on their own can withstand this heat, the other engine parts surrounding them may not. Adding a coating of protective header paint will dramatically decrease heat output to more forgiving levels. This alone can add years to your car’s paint job’s longevity, not to mention the other parts themselves. Bottom line, paint your headers if you want them to last longer.

Prevents discoloration

Rust is ugly, especially for a car enthusiast, and painting your headers will prevent this from ever happening. Adding a layer of header paint will not only make your header aesthetically pleasing but be protected as well. Rusted-out headers can be dangerous to run, not to mention expensive to repair. Discoloration also happens to the hood of the car itself. Luckily a layer or two of good quality header paint can save you from having these problems in the long run.

Prevent corrosion

The manifold and your headers are often not just exposed to extreme heat in the course of its life, but also the elements and chemicals in the engine bay. When bare metal when exposed to moisture and the elements for long periods, it gets rusted out. This is where good quality header paint comes in; it creates an impenetrable layer that protects vulnerable metal parts from being corroded. The coating is not only effective against water but other fluids as well, like oil and solvents. Additionally, it also protects against small debris and particle impacts as you drive along the road.

Improved efficiency

When an additional coating of heat-resistant header paint, you contribute to how your vehicle manages heat efficiently. Heat is what mostly contributes to speed up wear and tear on parts. With the coating, heat is contained where it is supposed to be, which is inside the manifold itself to be taken away by the headers to the exhaust tip. Because of this, the exhaust action will be sped up, and there will be decreased backpressure resulting in an overall improvement of the engine’s efficiency.

Protects other parts

One of the signs of poorly managed exhaust and heat dissipation is the faster discoloration of the hood paint, but that is the least of the worries that will arise from this. A bare header without adequate coating can radiate heat to other vehicle components, such as the electrical wiring, plastics, and tubing. While these are rated to withstand higher temperatures, the extra may push them to experience temperatures above their rating, causing damage. Adding that header paint coating will drastically decrease the chances of this from happening.


To ensure we are covering all the basics, here are some of the most common questions about header paint and their comprehensive answers. Take a look at them below.

Frequently Asked Questions (FAQs):


How long do painted headers last?

As a rule of thumb, a good quality header paint can last for three years on average. Still, advances in color and materials technology assure us that it can last even more, especially if correctly applied. Like any other paint job, surface preparation is essential for proper adhesion and the correct curing times.

If done correctly, header paint can last for several years, providing protection as well as aesthetics to your ride.


How to remove temporary header paint?

Header paints still behave like any other paint, after all, but just a whole lot tougher. They are formulated to resist oils and solvents, so ordinary paint strippers will not work on them.

Prepare an industrial or aircraft-grade paint stripper and apply it in much the same way you would in a standard paint removal situation.

After the allotted time has passed, apply some elbow grease, and the job is done.


Do these paints have UV protection?

While this is not unheard of, it is often rare to find this feature in a header paint product. For starters, the header and the manifold where these are applied are usually internal, where the sun’s harmful UV rays will not reach.

There is simply no pressing need for this feature to be incorporated into these products. This header paint has thermal protection as well as physical protection for wear and tear for your headers.


Are stainless steel headers better than ceramic?

Good old stainless steel wins by a large margin over those products touted as being ceramic. These ceramic products are, in reality, just mild steel that is coated with ceramic. While this gives them excellent thermal resistance, they do not offer anything by way of strength and corrosion resistance.

On the other hand, stainless steel offers both strength as well as protection from corrosive components. When you apply header paint to stainless steel headers, you add that tough layer of protection that also has thermal insulation properties.


How do you apply header paint?

Header paint is applied the same way as you would paint, and the secret to painting anything is to prepare the surface for maximum adhesion. Properly mask off any surface where you do not want the paint to stick to and carefully remove any contaminants on the actual surface that you would be painting.

The first step is to remove any old paint on the surface if there are any; this would involve an industrial-grade paint stripper or sanding, whichever the case may be. Next, ensure that there are no oils or chemicals on the surface to ensure proper adhesion. Remember that each product may vary as to how far the sprayer should be from the surface or how many minutes you need to wait before each coat. Because of this, read the fine print on the can of product you will be using for any special instructions in the application process. Once you have done that, you are good to go.

Conclusion

There is no part of the engine that has no reason for being there, and the header is a crucial part of any engine. While it may be tempting to just go right ahead and paint it with any paint, you may inadvertently ruin your engine. Ensure that you add years to your car’s longevity by applying high-quality header paint on your manifold and headers. Our list above is by no means a final list as the market and technology on these products are fluid. However, getting your hands on any of the products above will make you a sure winner in the header paint category.
