      Yes Flourish, the bonnet and hood is the same thing. A car bonnet is the metal part that covers the engine of an automobile. The term car bonnet is a British term, used primarily in England, Ireland, Scotland, Wales, India, New Zealand, Australia, etc. Bonnet comes from the Old French word bonet, which means cloth used as a headdress.

      Very helpful advice and I like the visuals. Is the bonnet the hood of the car?

      Crazy man! Never ever had the problem. I have my fluid aimed high so they hit the windshield but also spray all over any SOB who is tailgating me. And "a friend" suggested I keep it high in ammonia content as it thwarts the dogs from finding your stash. Not that I would know.
