You know those people selling Photoblocker to block red-light camera and toll-booth camera. Well, I bought a can of their paint and followed their direction to the T. They claimed that the more coatings you apply, the better the effect will be. So I use 8 coatings (they recommend 4 or more for best results). The following are the results. In terms of angles, I was assisted by a buddy of mine who is an OPP officer (police officer). Here's a direct shot Here's a "traffic camera angle" shot Here's a "toll booth angle" shot As you all can see, it doesn't do anything... well, it does do one thing great, it makes my license plate looks brand new and shiny.
