HMG Paints has played a pivotal role in an exciting discovery, confirming that a rare 1935 Aston Martin Mk2 Sports Saloon, chassis F5/585/L, was originally finished in a metallic green polychromatic paint.

The finding marks one of the earliest known uses of metallic paint on an Aston Martin and is a significant piece of automotive history.

The discovery was made during a detailed investigation at HMG Paints’ Manchester facility, attended by Aston Martin historian Steve Waddingham. The investigation involved a painstaking analysis of original panels from the vehicle, which had been restored.

The HMG team, led by chairman John Falder, included the HMG color library and Classic vehicle specialists, used a variety of techniques, including film thickness measurements, detailed chemical analysis, and both visual and microscopic inspections.

The team’s detailed inspection revealed a paint system consisting of a dark turkey red oxide primer, followed by coats of pale grey primer filler, and finally, several layers of the green topcoat. All layers were identified as a nitrocellulose system.

After a thorough analysis of the different paint layers on the car, which included original and re-sprayed areas, the HMG team, in collaboration with Waddingham, concluded with certainty that the vehicle’s original finish was metallic green.

“We were not expecting the polychromatic green to be the original color, but all the evidence points to that being the case,” says Falder. “These panels are some of the very earliest HMG have ever seen finished in a metallic color. This clearly would have been a special order when the car was constructed, and in our view, this is an extremely rare and very early use of polychromatic (metallic) paints.”

The collaboration between HMG Paints and Aston Martin highlights HMG’s deep-rooted expertise in paint systems and its ability to provide in-depth historical analysis for classic car restoration. This project showcases HMG’s commitment to supporting the preservation of automotive heritage and its role as a trusted expert in the industry.

“It’s really rather exciting,” Falder adds. “It was a fascinating day and a surprising result… not what I was expecting to see.”

The 1935 Aston Martin Mk2 Sports Saloon, which has now been fully restored, was one of the stars of the show at the 74th Pebble Beach Concours d’Elegance in California. The Pebble Beach Concours d’Elegance is the flagship of Pebble Beach Automotive Week. Commencing in 1950 and now considered to be the world’s premier celebration of the automobile, this is the ultimate event for every car enthusiast.

During the show experts critique the elegance, technical merit, and history of each car and crowds come from all corners of the globe to see icons of motor history. During this year’s show, the 1935 Aston Martin Mk2 Sports Saloon, chassis F5/585/L was recognized with the Monatagu of Beaulieu trophy, which is awarded to the most significant car of British origin.

This is not the first time HMG have been involved in a project with a vintage Aston Martin. They previously worked with Ecurie Bertelli, the pre-war Aston Martin specialist, for a one-of-a-kind project conserving a 1934 Aston Martin MKII.

The 1934 Aston Martin MKII chassis number 402, affectionately known as “Hedgehog” was preserved using a special stabilizing and sealing solution developed by HMG that allowed the Ecurie Bertelli team to seal the worn paint work and prevent further degradation. This unique approach allows 402 to ensure its vintage charm and character remains for years to come with its original paint work.
