Hey I've a question for everyone. I heard a LOONG time ago of a guy that was speeding in excess of 20+ over the limit. Is was clearly a speeder and so the cop on the side of the road clocked him, which he had nothing. The cop was a typical Highway Patrol and pulled him over, doing a through search for a jammer and eventually let the guy go because he couldn't find one on the guy. How/why? The guy had custom made his car with a coat of metal that reflected the radar back, thereby effectively jamming the signal. I've scoured all over the net and can't find that metal. Any chemists here that have any idea?
By the way, it WASN'T a spray on (although I'm curious how much those actually work)
