Swingarm paint

[YourOldNemesis]

I need to do a little bit of touch-up on the swingarm. Theres a patch behind the axle bolt about 2" square that needs re-doing as the paints all flaky. I think is't a small enough area that I might get away with touch up brushing rather than the palaver of spraying. Can anyone tell me what the silver colour match is and where to get it? 2002 M620ie silver....


Thanks
