Invisible coating for parts of vintage cars wanted... and found

With the support of Sirris, Cebo looked for an invisible coating to provide restored engine parts of vintage cars with an additional protective layer.

Cebo Automotive specialises in repairing cast, light-metal engine parts for vintage cars. For this the company, based in Ingelmunster in West Flanders, is relying on a cleaning and restoration process it has developed itself, making original vintage cars look good as new again.

Cebo wants to stand out from the crowd on the vintage-car restoration market with its guarantee of restored parts that look good as new for as long as possible. Therefore, the company decided to add a protective layer to the surface of the light-metal engine components. This coating needed to be not only transparent – so that the parts maintained their original appearance – but also able to withstand searing temperatures of up to 200 °C. However, Cebo preferred to avoid outsourcing the work applying the coating. In other words, the cost of investing in a coating facility for this purpose should not be too high.

The acid test

Based on the technical specifications, Sirris drew up a list of possible coatings. Then in consultation with Cebo, we narrowed them down to a shortlist of five contenders. In Sirris's Smart Coating Application Lab, they were each applied to aluminum sheets which Cebo had treated using the vintage-car restoration process. The sheets were then subjected to a series of trials. In this way we assessed not only the coatings' heat and dirt resistance but also their chemical resistance, gloss, and hardness.
