OK, I just heard about this from a colleague, thinking it was an April fool at first. Anyone here heard about a clear spray you can apply to your license plates, which make them reflective/unreadable to speed cameras?
Does is work? Surely not!!!

Heard the same thing about two years ago. And read some
article about the spray, plastic covers etc.
The bottom line was that none of the items worked. Just
another scam to get money out of your pocket.

LOL,.... I have several bottles of that stuff that I tried here,.......

Total waste of money as it didn't work at all. I coated 3 plates exactly per the instructions then proceeded to shoot 20+ pics with my Nikon F3 and SB-20 flash from all heights and angles.

All pics came out very nice and the plate was quite legible,.....

Had a friend try it and he son managed a ticket right away. So, I guess that would be a no vote from me.

I "heard" that Janet Jackson had it sprayed on her Boob. No one saw that did they?

Thanks, well I guess thats money well saved....

I always thought it would be good to spray the whole car. If it's invisible, you won't need to wash it as often.

Must be from the folks that brought us the spray to make your bald spot go away

Related Query: Has anyone tried those clear plastic plate covers that claim to obsure the auto-cameras? I'm dubious but who know until you test....

Randy:

ROFL,...they don't work at all, either.

Tried them, as well.

I think the ticket camera uses a high intensity strobe that would cause the clear to cause a blur. I couldn't get a straight answer from asking a photo pro.

Now if someone made a photo reactive paint that would instantly turn black when a high intensity flash struck it. I just don't think it would turn fast enough. It would have to be awfully damn quick to beat the shutter!

I don't know what the answer to clear spray is ?

but Popular Mechanics has been running an add for the Phanton Plate spray for a few months.. the add says
"tested by Denver Police Dept. and Fox News"
" Supriseingly effective... says Fox News"

and FWIW a friend told me yesterday that he believes an old small boat radar unit will jam PD radar.. no hard info on this.

of course the radar jamming is for theoritical mind exercise only.

RoninLB

there was a military radar absorbing paint additive on the market a few years ago. The info gave details about metalics in routine car paint, etc.
I couldn't find the additive last year.. sorry

I have heard that the plastic or lexan plate covers will defeat laser. The laser is in the IR wavelengths which are absorbed by the lexan. I know this to be true as we have used lexan in the past both test laser tissue cutting devices and for safety shields on CO2 lasers.

The dominant reflection for laser is from the plate since they have a coating with lots of tiny retroreflectors. Since the laser needs to pass through the lexan twice you get a decent path length for absorption.

Using a cloudy plastic plate cover may help with photo as the scattering might overcome the reflection. You could mount a strobe that triggers when the flash from the camera goes off thereby 'blinding' the camera. I think they photo from different angles at different times which might overcome this idea.

You can buy welding eye protection that darkens automatically with light applied, but they are only a few inches square.

Any anti-reflective coating over a reflective surface for a given wavelength needs to be 1/4 of the wavelength thick to destructively cancel the reflection. 1/4 of the radar wavelenth is very long, thus making the coating very thick.

Best to drive legally and worry about something else. This will help you and your fellow drivers in the long run.
