    We'll for my part, since I don't believe this was done intentionally by Mirage or RALETC, I will couch my emotions (for a change). I would merely like to state what I believe Mirage has actually shown here with his "absorption" test of Veil G5.

    Basically what Mirage has done is taken the entire energy of the laser, something that has been designed to measure distance in the thousands of feet in broad daylight and concentrated it intensely into one small circle at several inches at point blank range and in doing so has demonstrated the following phenomenon:

    I have had a tremendous amount of respect for the past efforts of RALETC and I appreciate the time that Mirage has invested in trying to understand (or demonstrate) the mechanics of G5 and I also believe, at this point, that he is well intentioned, but my suggestion to those that would like to test Veil to at least test it in its intended use--on a test course against a police laser conventionally operated or on the open road against real LEOs.

    And please listen to me when I say this, one coat of Veil G5 on the headlights of the vehicle is entirely sufficient. To suggest that five is needed before any real effect can be realized is flat out inaccurate and misleading.

    So what happens when the headlight is operating and throwing huge amounts of IR at the housing and at the Veil that coats it? This is especially true of old style halogen headlights which put out most of their energy in the IR spectrum. Are you saying that the Veil will be much less effective when the headlight is on?

    If this is the case, then the tests should include:
    1. No Veil on the lights
    2. Veil on the lights, headlights off
    3. Veil on the lights, headlights on

    Oh, and then what about the strongest IR source in the Solar System, also known as the Sun? What if it's ahead of the car, shining very brightly onto the headlights, and then a cop shoots the headlights with LiDAR? If you've got saturable absorption issues from a weak LiDAR gun, I'd hate to see what happens when you add the Sun to the mix.

    One coat on the headlights is sufficient? What about those of us who run front plates? Given your statement in this post: http://radarandlaserforum.com/showth...ll=1#post49751 it's clear that you are of the opinion that covering just the plate but not the headlights is insufficient. The converse of this statement is that coating the headlights but leaving the plate uncovered is just as useless, because you'll get an IPT from the plate reflections alone. That said, how did G5 make it to market apparently without testing it on license plates? We've all seen this image by now:



    So we're all supposed to drive around with plates that look like that in order to be properly protected? And even then, only if the Sun isn't hitting the plates or our headlights?
