Hi, I am a new club member, and just saying hello! I have a 2010 XKR , in ultimate black, and its the best car I've ever had. Knocks the previous Mercs and Beamers for six! However the only fault on it, is that the window trims, which are chrome coloured, have a sort of watermark/discolouration which is unsightly and impossible to remove, as it seems to be under the finish. Does anyone know if these can be replaced?, either with new chrome ones, or matt black? Thanks Kev
