License plate spray to emulate (PhotoBlocker) existing products

I want to learn how to make my own photoblocker spray so I can use the tollway without my plates being photographed. I know PhotoBlocker already works but wondering if you geniuses can come up with an at home, DIY for this purpose. MANY thanks!

Blue led photography...

I just took some new pictures for my BraceLED 2.0 I'ble. And look at the picture of the bracelet with the blue LED's! The reflection of the blue light on the white surface (=paper sheet) is highly overexposed! How does this happen? Is the cmos sensor in my Nikon D300s over-sensitive to this color of blue? A picture of a red-led-bracelet under (almost) the same conditions has no such effect. Picture red BraceLED: iso800, 35 mm prime, f/4, 1/20 Picture blue BraceLED: iso800, 35 mm prime lens, 1/15
