Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

yes, they do work. Basically the plastic has a prism type effect on the surface which reflects in a way that the plate is not viewable from the typical angle at which traffic cameras are set up.
i saw a test of these types of materials in some magazine a while ago, I can't remember which maybe Car & Driver. In any case they showed that it doesn't really work. Just another perspective.
Myth Busters did a whole episode on these and they DO NOT WORK!!! Top gear crew only managed not to get photographed by the camera when doing over 180 MPH in FORD GT I believe. Don't waste your money IMO.
There hasn't been photoradar in Ontario since 1995 and within Canada I believe it only found in Alberta and Manitoba.
I've also seen the reports that say it doesn't work.
Neither the film nor the spray work. The local (D.C.) NBC affiliate had a segment on it a while back. They tested both the film and the spray using D.C. speed cameras. At first you couldn't read the plate but by running a simple image filter the plate was clear as day.
Great gimmick, but even if you somehow installed one of those, how would you be able to activate it in time? You'd have to know the location of every camera. Or you could drive around with the decoy plate showing all the time, I suppose, but then you might as well just stick a bad set of plates on the car and hope for the best (because it's a crime).
I too believe they do not work.
Some of the stuff out there (i.e. ghost plates) is similar to the monitor devices that stop people being able to see from an angle what you are working on, but straight on it is visible.
With today's digital cameras and technology, I agree with Tim, paint the plate black to know for sure, or remove it, then you have no doubt it will work and you haven't wasted your money on a gimmick.
The plate covers are BS.
Depending on the state you live in. I drove around in California for 3 years with no front or rear plate on my car. I just keep the dealer registration sticker in the front window. I was NEVER pulled over or questioned about it.
However that is in California where you have to wait for your tags to come in the mail, you do not drive off with them at the dealer like in some states.
