Even i have been seeing this a lot in. Saw this on VW, Skoda and even on a Logan!!
You cant imagine how i hate those people who does that to someone's car. Not sure if you guys have watched a movie "Jackal" a Bruce Willis + Richard Gere starrer. In that movie Bruce Willis gets out of his SUV and takes out a can and sprays it on the boot handle knob and leaves. The thug who was following him checks his vehicle and as soon as he touches the boot handle knob falls to the ground vomitting blood.Nice thought na! :-). I really hope that the re was something like that really available in the market. That wud be a befitting reply to all those theives.
