Mythbusters disagree:

Sub Myth 2: Plate Blockers

It is possible to obscure your license plate from a speed camera without obscuring it to regular vision.

The Action/Results:
They test 5 things that are supposed to keep a speed camera from getting a clear picture of your license plate. Two are DIY: clear plastic wrap and hairspray. The other three are commercial products: ?blocking spray?, a plastic plate cover with microcrystals to reflect the flash, and another plate cover with a plastic lens to distort the license number.

Adam sets up a scale test in the shop, using his digital camera and flash. The only product that does anything is the plastic lens, but there is still enough of the license number clearly visible for a database search.

The test is then repeated out at Alameda. Once again, the lens blurs out part of the license number, but not enough to do any good. The other products don?t do anything. Myth BUSTED.
