^ Yep, "plate-cover" laws, even in areas which have them explicitly on-the-books, is enforced in a rather "discretionary" method, and is highly variable.
Typically, outside of some specific covers being countermeasures (of varying levels of effectiveness) against various traffic-enforcement methods, most are actually aesthetic accessories, and some even are gasket-sealed, to preserve the enclosed license plate, and are often a favorite of auto-enthusiasts in more "corrosive" environments.

VEIL will still cut the IR-reflection from the "dressed" plate, but in applying it directly to the plate, some caution should be exercised:
First, you'll want to test to see if the paint (including the printed ink of any registration/ownership stickers that go on the plate) is stable/compatible with VEIL. We've had reports here, Stateside, of various state's used inks, either for the plate or for the stickers, being literally "washed off" by VEIL - both G2 and G4.
(2) That the VEIL coating of the plate is not only aesthetically acceptable for you, but also, will not present to your local enforcers a "huh, that's not right!" kind of moment, and cause you to either bear a citation, or otherwise be stopped for a "roadside interview."
In comparison to a naked plate, covering it with VEIL will definitely drastically reduce the item's IR-profile.
However, in comparison to dressing an overlying "plate cover" with VEIL, it is speculated that the direct-dressing application may not be quite as effective, as the overlying layer of VEIL on the raised plate-cover would not only give a "first pass effect" (i.e. be the first point of contact of an incoming LIDAR beam), but also would exert an effect during the "return" process, as the LIDAR's scattered beam, from having now passed through and contacted the plate, would then be "reflected" back to the police LIDAR device.
Unfortunately, I do not recall any actual data to cement this theory - perhaps
VEIL Guy can be of assistance in digging this up?
