Always good to get a more indepth thorough answer and learn how they were all finished. Thanks SecluffJohnJ. depends on which one your asking about. If the engine oil dipstick, black handle on the Boss engine, Ford Blue on all other engines. The transmission check stick is a natural finish or phosphate and oil.The power steering pump check stick/cap on my cars are a silver finish (not painted). The yellow handle look is something Ford started in the late 80's.
EDIT...John guess I need to check into getting some glasses. Just as I posted my answer I saw where your post header had "Transmission Dip Stick"!! :whistling:
