I am just in the process of bringing my recently acquired 2012 R1200RT back up to scratch after buying it for a bargain price because it was in such tatty condition. Considering its only 2 years old and done only 24,000 miles, it looks more like a bike double or triple the age between the corrosion on all the bolts, cylinder heads (BMW should be ashamed) and the wearing of all the silver paint above the footrests.
I've got replacement bolts on order, but wanted to ask for the wisdom of the forum in terms of best way to restore the silver bits. The picture below shows how the paint has worn through.

I was thinking just take the piece off as it looks easy and respray the whole piece, but where can I get matching paint from? The only colour code I know of is for the fairing colour (Midnight Blue) which is no use here.
Can anyone advise?
