just had a play with some paint i bought for my daughters radio control car , if its sprayed onto lexan it gives a chrome effect (very good) ive just been playing and if its sprayed on a good surface then lacquered it looks good , not as shiney as chrome but a lot less hassle and available from any model shop.
Martin's mate did a fantastic job on my "I" and "C" grille pieces I would highly recommend him to anyone! Also he can do colours too Gold,Bronze,Blue etc which look amazing on the samples he showed me
