  • Top High Temp Paints and Coatings

    One of the biggest eye sores on a vehicle can be the areas that are exposed to high temps during operation. Exhaust tubing, Headers, Firewalls, cylinder heads, block, etc. can all become ugly quick with the extreme temperature changes they experience when running the engine. Some of these can be easily be spruced up, but choosing the correct coating for each spot on the vehicle can be crucial to how long those parts will stay nice. We decided to put together a list of our favorite high temp paints and coatings and where they are best used.
  • Choosing the Correct Coating for your Exhaust Manifolds

    A vehicles exhaust system can be one of the most common areas for rust.  The majority of all cars have exhaust systems which are completely exposed to the elements at all times.  If thats the case, any untreated steel components run the risk of rusting out fairly quickly.


    To ensure this does not happen to your exhaust system you may consider coating it to prevent any corrosion.  Sounds simple enough, but you wont be able to use a typical spray paint.  Normal enamel spray paints are only able to handle temperatures up to around 250ºF, far below the temperatures the typical exhaust components reach.

    In order to properly coat your exhaust so it will not rust you will need to use a coating specially designed to withstand the high temperatures exhaust components can reach.  Eastwood High Temp Ceramic Coating is capable of handling temperatures up to 1400ºF, far above temperatures that will be found in and around the exhaust system.  This coating contains special additives that make it very different from normal spray paint, containing small metal flakes that are extremely heat resistant.


    The preparation process is very similar to any other type of painting, if you plan to use this on headers or exhaust components we recommend that you take it down to bare metal to achieve best adhesion. To do this the part can either be media blasted or gone over with heavy sand paper.



    The first step in getting ready to coat this set of headers is to put it in the Blast Cabinet to remove all of the black shipping coating that is mostly warn off from only a couple thousand miles of use.



    After verifying that all of the coating was removed and only clean metal was exposed it is necessary to clean the metal.  Use a blow gun to remove any dust or blast material left on the manifold then wipe the part down with PRE Painting Prep.  Sand paper and blasting material can trap dirt and contaminants which can get left behind on the surface of the metal.

    All of the exhaust ports must be masked off because not only will this prevent the coating from going into the header, it will prevent any trapped dirt or dust from contaminating the coating during application.

    Once wiped down again with PRE Painting Prep, the part is ready to be sprayed.  Make sure you are in a well ventilated area and use proper safety equipment when dealing with any type of chemical coating.  This includes Gloves, a Respirator and Safety Goggles, when necessary.  All of the safety equipment you will need can be found right here on the Eastwood website.



    Apply 2-3 light-medium coats with about 30-45 minutes between each. Applying this product too heavy can cause durability issues and even flaking.  After the final coat the part must sit for at least 24 hours before it can be used.  After the 24 hours it can be put back on to the engine but before normal use it must be cured.  Start the vehicle and let it idle for about 20 minutes, the heat from the engine and exhaust gasses will fully cure the coating to achieve maximum heat resistance.


    The before and after results are staggering, now you can open your hood with confidence at the next show and not have to worry about those ugly rusty headers.  All of this with the added assurance that they will not rust out.

  • Protect your Exhaust Inside and Out- Eastwood Exhaust Coatings

    Rusty Header

    One place that many often forget when restoring a vehicle is the exhaust system. Like the rest of your vehicle, rust loves to hide in those hard to reach locations. Your exhaust system is no different. If you think about it, the exhaust is subject to some pretty harsh conditions. Not only does it see all types of weather, road salt, and grime, but it also will be subject to extreme temperature changes. These conditions help accelerate the rust both inside and outside of your exhaust system.

    We realize that working on your exhaust system is not a fun job, so we have developed a full line of Exhaust Paints that will allow your exhaust system to last the life of your car so you don't have to do the job more than once.

    The first step when installing a new exhaust system is to coat the inside of the exhaust (especially inside headers and manifolds) with Eastwood Internal Exhaust Coating. This will stop any rust that could be lurking inside your exhaust and seal out moisture from causing future corrosion. Internal Exhaust Coating also keeps your under hood temperatures down, giving added benefits aside from the obvious. This is a step that is often missed, but is necessary to the longevity of your exhaust system.

    Next is to coat the outside of your exhaust system to avoid external corrosion and also to keep it looking great! We offer a number of different Exhaust Coatings to give you anything from an eye-catching custom look, to an exact replica of how your exhaust looked rolling off of the showroom floor!

    So next time you do exhaust work on your vehicle, take the time to make sure your exhaust lasts as long as the rest of the project!
