They found it to be "surprisingly effective." The spray is invisible from a distance. No one will know that you have it on.
Ans. PhotoShieldTM is by far the better of the two products. It is designed to be subtle and stealthy. It looks just like a regular cover that you buy from an automotive accessory shop so that it does not attract any unwanted attention.
However, when a photo-radar camera mounted on the side of the road tries to take a picture of your tag, 2-3 letters and numbers will be blurred. Fox News called it "surprisingly effective."

Ans. We recommend that you use the PhotoBlockerTM Spray in conjunction with the PhotoShieldTM license plate cover. First, spray your tag with PhotoBlockerTM spray to protect you from unjust tickets issued by cameras that use FLASH . After it has dried, attach your tag back on to your vehicle and put the PhotoShieldTM cover over it. The cover will protect the spray coating from debris, scratches and most of all it will protect you from cameras that do not use FLASH.
