The law applies to plastic license plate covers, but I think the term is
devices. If you get pulled over for something else and they notice your
license plate has been tampered with, then they could ding you for that too.

This may be a scam anyway--maybe it's some spray on snake-oil thing. A
better and cheaper alternative is just don't get speeding tickets.
