We were at a car show one time where someone was putting bright pink flyers under the cars with windshield wipers. and on the seats of cars without wipers. Around 1:30, it started to rain. The pink from the flyers started washing off the paper and ran onto the glass and down the cowl, hood or fenders or out onto the seats. One guy had white seats in a roadster, no wipers. I don't know how he got those seats to be white again. Those flyers were not very popular!

I've attended a few shows because of the flyers left on my seat. Doesn't bother me much, buy then I don't have a trophy winning ride.
