   Check out radardetectorforum.org specifically the "passive   
   countermeasures" forum.   
      
   Most of the sprays are just useless.  There is apparently a product   
   called "Laser Veil" that does provide some benefit, but the drawback is   
   that it must be applied to both the license plate and any forward facing   
   lights, and it's a) tinted (undesirable, because it looks like you've   
   applied something, and also reduces the output of your lights) and b)   
   can be washed off by alcohol, which means that if you have headlight   
   squirters it'll ruin your application eventually.   
      
   Additionally, it doesn't completely prevent a laser speed gun from   
   getting your speed, it just buys you an extra second or so before it can   
   lock.   
      
   I see from your .sig that you're in MD, my best advice would be to run   
   Waze or Trapster on your smart phone to alert you to the location of   
   fixed cameras, and just try not to speed.  I know, it's hard with some   
   of the SLs in the metro DC area but there is no real defense against a   
   cop with a handheld laser gun other than an active jammer.   
      
   You could also run a good radar detector with laser detection   
   capabilities like a V1, but honestly the laser detection just tells you   
   that you've been nailed because of the nature of laser; even the best   
   detectors will only alert a fraction of a second before the speed gun   
   locks onto you.  That isn't legal in DC or VA (and neither is a laser   
   jammer) though as I'm sure you know.  The main use for that is to alert   
   you to the location of the cameras while you're driving legally so when   
   you drive the same roads again you'll be vigilant of your speed whether   
   or not Waze alerts you - it won't save you from a ticket.   
      
   I'm assuming that everyone knows that radar jammers are illegal   
   everywhere in the US, although to the best of my knowledge all the speed   
   cameras in MD are laser not radar.
