I ran across this article. Interesting if nothing else. Here are just two sections of it. The rest can be found at

"The "terrible" cars are all those using metallic films to reject solar energy. The main part of the Olds Silhouette windshield, and an Audi A8 equipped with the insulated glass, performed identically. They cut radar strength by 95 percent. That chops today's ordinary detector back to the protection of a 1977 Fuzzbuster, Valentine says, a time we remember as the reign of radar terror."

"Normally, these films would be applied to side and perhaps rear windows (state laws vary), although they could be used to add a tint band across the top of the windshield. If you're hoping your laser detector will find rear laser, keep all of them off the rear window. As for 360-degree radar detection, only Valentine One has a rear radar antenna, and it's the only one that provides useful protection in any direction other than front. Any metallized film on any window will definitely hurt Valentine One's performance and will also confuse its sophisticated and very useful radar-locating feature."
