Yup.... people have been using it to defeat camera radars ever since too.... the plate looks normal under normal light but with a camera flash it overexposes the license plate making it unreadable. People used to sell it on ebay about 10 years ago by relabling the cans as stealth paint...Durable reflective clear has been around a long time
