VHT paint application methods
VHT paint can be applied to chipped painted headers, but it may not be the best option for long-term protection. While some users have reported success with VHT paint, others have found it to be ineffective and prone to chipping and burning off. Here are some improved VHT paint application methods for better results:
Surface Preparation:
Before applying VHT paint, it is crucial to prepare the surface of the headers properly. This involves stripping any existing paint or coatings using a paint stripper or sandblasting. Ensure the surface is clean and free from residue, oils, and rust. You can use steel wool or, preferably, grit sandpaper (400 or 800 grit) for this step. Latex gloves are recommended to prevent transferring finger oils onto the metal.
Cleaning:
After stripping, clean the headers thoroughly to remove any remaining paint, residue, or oils. Use a lacquer thinner, applying it generously, especially in tight spots. This step is crucial as it ensures the new paint will adhere properly.
Primer Application:
Once the headers are clean and dry, apply a suitable primer, such as a VHT flame-proof primer, to the entire header. Allow the primer to dry completely, following the manufacturer's instructions for drying time.
Painting:
When the primer is dry, you can begin painting. Set up a well-ventilated workspace, as VHT paint fumes can be strong. Consider working outdoors or in a well-ventilated garage with open doors. Hang the headers or place them on a flat surface, ensuring you paint the underside first to avoid scratches during the curing process. Apply the VHT paint according to the manufacturer's instructions, typically using a spray application.
Curing:
After painting, follow the manufacturer's instructions for curing the paint. Some VHT paints may require baking in an oven at a specific temperature for a set duration. Be cautious when curing, as some users have reported yellowing or discolouration due to heat.
Post-Painting Care:
Even with proper application, VHT paint may require touch-ups over time, especially in areas prone to chipping or flaking. Regular maintenance and touch-ups will help extend the life of the paint job.
While VHT paint can provide a temporary solution for chipped painted headers, it may not offer the same level of durability and protection as other methods, such as ceramic coating. For long-lasting results, consider exploring alternative coating options recommended by automotive professionals.

VHT paint alternatives
While VHT paint is a popular choice for coating headers, there are several alternatives available in the market. Here are some options:
Cerakote Ceramic Coating
Cerakote ceramic coating is a popular alternative to VHT paint and is known for its durability and resistance to chipping and burning off. It is applied through air-drying and can protect headers from the inside and out. This coating can withstand high temperatures and has been known to last for years, even with regular use.
Nickel Coating
Nickel coating is a type of metallic coating that can be applied to headers for a decorative and protective finish. It provides a shiny, silver colour and can enhance the aesthetics of the headers. Nickel coating is known for its corrosion resistance and durability.
High-Temperature Ceramic Paint
High-temperature ceramic paint, also known as exhaust paint, is designed to withstand high temperatures and protect headers from rust and corrosion. It is important to thoroughly clean the headers and apply a header primer before painting to ensure the best results. This type of paint can be difficult to spray due to its watery consistency.
Sandblasting and Painting
Sandblasting the headers to bare metal and then painting them with high-temperature paint is another alternative to VHT paint. This process involves using a media blaster to remove the existing paint and create a smooth surface for the new paint to adhere to. This method can help extend the life of the headers and improve their appearance.

VHT paint preparation
VHT paint is a high-temperature ceramic paint that can be used to coat headers to protect them from rust and improve their appearance. However, some users have reported that VHT paint can start to flake or turn white over time, especially at significant bends in the header tubes. To ensure the best adhesion and longevity of the VHT paint, proper preparation is crucial. Here are some detailed instructions for preparing surfaces for VHT paint application:
Surface Preparation:
Start by stripping any existing paint or coatings from the headers. This can be done using a paint stripper or by media blasting, sandblasting, or wire brushing the surface to bare metal. Be sure to remove all paint residue and clean the metal thoroughly. It is recommended to use a degreaser or a lacquer thinner to wipe down the surface and remove any leftover paint, oils, or residue. You can also use steel wool or grit sandpaper (400 or 800 grit) for this step, but be aware that steel wool may leave fibres behind, requiring an additional wash. Always wear latex gloves during this process to avoid transferring finger oils onto the metal.
Primer Application:
Once the surface is clean and stripped, apply a suitable primer, such as a VHT flame-proof primer, to the entire header. Allow the primer to dry completely according to the manufacturer's instructions. This typically takes around an hour and a half.
Painting Environment:
Set up your painting environment in a well-ventilated area to manage the potent fumes produced by VHT paint. Consider working outdoors or in a space with open doors and windows. Protect surrounding areas from overspray by using a flat piece of plywood or hanging the headers to paint them. This will also help ensure a consistent finish on all sides of the headers.
Paint Application:
With your surface prepared and primed, you can now apply the VHT paint. Be sure to follow the manufacturer's instructions for application, including recommended drying times between coats. Depending on the paint colour, you may need to bake and cure the headers after painting to ensure proper adhesion and prevent discolouration.
Remember that proper preparation is key to achieving a durable and long-lasting finish with VHT paint. Taking the time to thoroughly clean, strip, and prime the surface will help ensure the best results.
