Porcelain Coating

Porcelain coatings for automotive manifolds go back to the 1920s, or before in some cases.  Stoves have been porcelain coated for years before that. Simply put, a porcelain finish is second to none for creating a finish with luster that can sustain high heat.  Porcelain is a vitreous enamel coating that is fired at over 1400 degrees, creating a smooth and shiny durable finish that has superior heat resistance properties than other high temp finishes.   Our process is one that has been refined over time, and yields consistent results for customers.   While many things can contribute to longevity of finish, starting out with a consistently applied coating starts you off on the right path from day one.

We have been fortunate enough to maintain our quality standards over the years, and in turn be able to rely upon return customers.  Our company services all walks of collectors, and among them are those that road and tour Duesenberg Model J's, Jaguars, and Indian Four's, as well as those who still want to fire a wood stove and need a finish that can stand up to the heat.  While we provide standard black & white coatings, we also maintain and sell a proprietary Green blend for Duesenberg automobiles that is the same that we've offered for decades.  We are THE known quantity in porcelain coating. 

Pricing will be determined by a number of variables, including: complexity of the design of the manifold, size, weight, etc. Pricing may be estimated via phone/email correspondence.  Some cast iron pieces are, by virtue of their casting composition, not suitable for coating, and in the rare case of this happening, we'll consult with you prior to fulfilling any services.  We reserve the right to inspect the parts upon arrival and may revise pricing upon inspection if the piece requires additional services not anticipated upon the initial consultation.

Is Porcelain right for your project?  Here are a few things to consider.

  • Our porcelain finish is on everything from Jaguars that tour year after year, to Pebble Beach shown Duesenbergs.   Longevity of the finish, when gauged against use, tends to trend towards a longer lifetime when it is not exposed to wet conditions when the manifold is hot.

  • Ceramic coating, while more all weather condition durable, does not and cannot mimic the shiny luster of porcelain.   This finish can help push a car into the winner's circle.

  • Lifetime of finish also is impacted by other factors such as manifold design and how well an engine is tuned.  An engine running too lean or running with the timing too retarded will expel exhaust gases at a higher temperature that can impact the coating due to more expansion and contraction.
