An old trick to protect your shiny new bike is to slap loud and uglypaint all over it. Much more subtle is Dominic Wilcox's temporary ruststickers, that are "designed to make your beautiful bike/car lookrusted and scratched so that passing thieves assume it's not worthstealing due to its apparent shabbyness."
The inventor notes that he put them on his new bike 13 days ago andit has not been stolen yet, which he considers "probably equates to 7years of non-stealing in the friendly countryside." Only £3.99, a lotcheaper than my lock....
