So far, so I hear, this is legal because your license is still perfectly visible to the naked eye and there is no law against a sparkly plate.  So here you go...PhotoBlocker license plate spray. Grab a can and douse your license plate. The special formula produces a high-powered gloss that foils red-light and speed cameras as the gloss reflects back the flash from a camera, overexposing the image of your license plate. One can covers four license plates.

But don't take the spray as license to zoom through intersections all over town. The makers insist that PhotoBlocker is designed to protect drivers from faulty cameras only. "We do not condone the use of PhotoBlocker products to defeat toll booth cameras … Always obey traffic laws," the product advertisement says.
