Does it work?
I've never tried the spray. There used to be a "clear" license plate frame available that only allowed the plate to be seen and readable if you are perfectly perpendicular to the plate, the view was distorted from any other angle. I think the states outlawed them IIRC.
It's illegal in some states on plates (AZ). I don't know how well it would work. I see stuff going both ways.
If somebody took the time to make it illegal, it must be at least somewhat effective.
Not too many readers out in the boonies where I live.
That's my take on it, too. They scan our plates in our parking lot at the stupid complex I'm in so I took a look to see if it was illegal to do and looks like some rep in Tucson got all butthurt about it a few years ago. It must work or at least make more work for a cop so they have to be head on to see it.
