License Plate Camera Anyone Use License Plate Concealer Spray To Protect Themselves From Police Camera's?

Anyone use License plate concealer spray to protect themselves from police camera's? - license plate camera

I've heard of these things are installed as a safeguard against this by the police cameras provide a picture of the license plate and take a ticket to the registered owner of the vehicle.

Anyone ever buy any of these before spraying? Can I do the same if I have a shiny or matte clear coat sprayed on my plate instead of paying $ 25 for a can of it?

Who's using on here?
