Whoda thunk it?
If this were some planned event to demonize Scott's critics, wouldn't it make more sense to leave the defaced sign in place for a while? How long does it take to make a sign anyway?
Let's see here; assuming no appliques (such as the seal on the lower left), there's the base white coat, then let it dry. Then there's the border, the lettering (Scott's name is a different color and larger font than the rest), the seal. Speaking as a modeler, not a sign-maker, it's generally considered a good idea to mask off and apply different elements as separate steps, allowing the paint to dry before the next step. Back of envelope guesstimate: five steps (base, border, black font, blue font, seal). Six if you add a sealer on top of the work. Six hours minimum, and that's pushing it.Perhaps there a super-quick-drying coat for sign making, or maybe the whole thing is a single, giant applique. But I'm guessing not.
