Forget plasitidip, it'll come off the chrome plating eventually as it can't key in to the chrome surface well enough. Where are you? If you're not too far off - I'm in Wigan, Lancs - you're welcome to drop them off and I'll do them for you. Failing that pm me and I'll let you have my address and you can post them to me (badges - not bumper). Some shots here of mine, I use a vinyl spray which I've found to be quite good so far http://www.dewisant-photography.net/y_ogb_BMW_Z4.htm
