According to a Utah HP officer, jammers do work... Unfortunately some of them put out too much signal and cook the radar gun.

He says when his display suddenly goes dead, he looks around very carefully and when he finds the guy, the citations, fines, impounds, and radar equipment replacement bills (with labor) make all speeding tickets look tame.

On the other hand, apparently flat black is pretty good at absorbing the laser.

The newest radar (according to my mole) has a secondary frequency broadcast that causes a patch of asphalt to re-radiate a signal as well for a good comparison. It seems to be worthless in heavy rain, so if you're into serious hydroplaning...

Supposedly iron oxide is the active ingredient in radar absorbing paints. Rumor has it that it was inspired by a Japaneese artist who got hold of way too much magnetic tape somewhere and wrapped a bridge with it. Ship captains reported that the bridge disappeared from radar screens. Supposedly it turns microwaves into static electricity.

There's also microwave absorption material inside microwave ovens. If you've got a fiberglass snake and a hankering to undercoat the underside of your non-metallic painted car with it, you might have something. The radiator and headlights would still be a problem, though.
