For the engine bay, since day one, I hose it down. You don't need all that jazz if the car is purchased new so.......I use armoral on the engine and have on all my cars since 1984 ! That's correct guys.....Aromoral ONLY on the engine bay, not in the car ! That's a whole different topic.....Ask some of the Bay area members, if they remember how clean my engine was having 45,000 miles on it ! Bobabwaw (spelling) saw it, you can eat off my engine ! Once you start that, then all you have to do is, wipe it down and apply ARMORAL ! Try it, you may like it !:wave: :wave: :tongue:
