Part number required (touch up paint)

Hi all

Does anyone know or can find out the part number for the Renault touchup stick thingy for my 200T.
Its for the silver blade on the front bumper that has a rather annoying stone chip on it.

thanks
Gav
 
I've tried getting a touch up stick from renault before for my ultra red but they don't do them for the 197's for some reason
 
OK I have managed to find the paint colour, Renault don't supply a touch up kit the colour I need is Satin Chrome 205338 any idea's where I can get a small pot of this paint from?
