I have recently acquired my 2010 RR 5.0 SC Autobiography Overfinch

The plate next to the suspension turret where the paint name is displayed says Autobiography White. However, I do not see this listed in RR paint colour charts.

On the slam panel is another plate where it say Paint Code L09K.

The colour itself looks like a pearl white.

What do I have?

Further digging and it appears the paint is Bentley Silk White Metallic. The L09K is on a Land Rover Special Vehicles plate so I guess it was some arrangement between Land Rover and Overfinch.

According to my trade paint supplier L09K is made up of a light grey primer, then a specific white 'ground coat' base, then a transparent pearl, then lacquer.
