Ouch, I was trying to be helpful. I thought this may have been one of your first ventures into the police fleet graphics area... We do a decent amount, and have never done one w/o reflective. But, it's always been specified that way by the departments. I do agree that most police striping packages we create or modify are boring, but around here in NKY it's more about conformity than looks.
Post up a link to your city's website or pics of other officer vehicles in your town w/o reflective on them so I can see what they look like.
