Hello All, Ever considered using the old model T ignition coil approach? Basically hooking +6 to +12 to the primary and hooking the secondary to the vehicles body. Whenever someone touches anything on the car they get a high voltage shock. It does work. To make it even more effective with today's technology, hook a motion/shock sensor up to activate it. This is an effective set-up and it'll even stop animals from excreting on your car. Funny story, I seen a dog piss on a car with this set up and it made him yelp and fall unconscious. After that, the dog was deathly afraid of the car. With today's technology youcould also make a remote for it and shut it off instead of the hidden switch idea (plastic handle, of course). Just my two cents. Frank |
