I've only ever heard of points being deducted if your hood wasn't open, no matter what condition the cleanliness of the engine compartment.
Congratulations Arlie!
I keep a first aid kit in my ambulance(duh)...and I also have a Los Angeles County Coroner bag with an emergency road kit for the car in it. When I attend any car shows with my Professional Car Society club, we must display a fire extinguisher and all lights are checked, signals, brakes, reverse, headlights , but not the emergency lights. All windows must be up and not cracked or missing. The hood must be opened but may be closed after the judges look at it. I was shocked at the first west coast international meet held in CA in 2007 where I placed third in my category and I had never shown it in a ProCar event before. I had no idea what they required for their judging before I got there.
