GS cylinder head touch up

[DrPete]

After my tarmac surfing the other day I see that the nearside cylinder head has a couple of small 2cm scratches that seem to have gone through the paint and exposed the mag underneath.
Is there a touch up paint for such an occurrence, and if one of you has a BMW part no I'd be very grateful. Presumably it's the same as for the frame? Alternatively - do Halfords or other aftermaket paint vendors do something suitable?

Don't know about the 1200 but on my 1150 I used Hammerite Smooth silver to touch up the heads after a small off while off roading - the useless Touratech head guard protectors ate the paint work off. Hammerite is a good match and will take the heat.

Excellent - thanks! Cheaper than oe as well.
