There's "documentation" on both sides of the coin to prove and disprove thta the sprays and covers work or don't.
Here's the problem. In Florida it's ILLEGAL to put a cover over your plate that deforms, disguises, obscures, etal, any portion of the plate. Some people have actually received citations for simply having a border plate that covered part of the tag (the "florida" at the bottom, etc).
Of course, if I were the officers supervisor, we'd be having a little come to Jesus party (I'd get to play Jesus
) about his role in law enforcement and life expetancy on my squad
Regardless, it's illegal.
Same goes for the spray. The biggest issue with the spray is proving it
I'd opt for (and if we get these damned things, I will!) the spray.....
