Layered clothing can save your ass. About two weeks ago I fucked up completely and ended up finishing my 3d under the spotlight of a cruiser. I ran and stupidly hit a dead end. (Always scope shit and know where to run...) Ditched my pants and shirt in a dumpster and walked right past the cops. Obviously this was largely thanks to luck but if you have to, be polite but confident as hell like you are a middle aged WASP who got pulled over for an inspection sticker on the way to sunday service and don't let them see you out of breath.
Then again, if this shit isn't naturally occurring to you, maybe you shouldn't be going out painting.
Just curious... Why were you driving around just to put up stickers?
