Dominic Wilcox’s Anti-Theft Bike/Car Device is a genius idea. Clear stickers which contain rust and scratch marks, which you place on your property to make it look too old to be worth stealing. Not sure how it would work on a 2009 Porsche, but on a bicycle or aging car, pretty good? Of course there’s people who’ll steal the rust off your tractor for a sweetie, so it won’t always work. Lovely idea though, and worth a punt at £3.99 a pack.
These rust and scratch stickers are designed to make your beautiful bike/car look rusted and scratched so that passing thieves assume it’s not worth stealing due to its apparent shabbyness. Note. This anti-theft device is not guaranteed to work in any way. However I have stuck them to my shiney new red bike and can confirm it hasn’t been stolen yet. 13 days of not being stolen in London probably equates to 7 years of non-stealing in the friendly countryside.
Why not save $5.80 (as a start) and just drive an old beat up car that no one (strike that! In this economy, let's just say most people) would not want to steal? Besides that, in an older car, you'll feel better when you get those inevitable first real nicks, dents and scratches on it.
Oh, and don't stick rust stickers to PLASTIC bumpers, like in the picture :)
