Substitute for the MS-5

Hi,

Does anyone now is the best substitute for the MS-5 - Metallic grey?, because I went to my local shop the they told me that they don't have, and it's out of production.

Thanks

MS-5 is still available from Rainbow 10 (http://www.rainbowten.co.jp), they'll ship aerosol cans internationally. In a pinch something like Tamiya's Gunmetal would do, if you're planning to use it on a McLaren.
