In Florida, small black bugs called Love Bugs swarm in the summer can be a nuisance to motorists, especially since these bugs are acidic and can damage a paint job. We were about to head north and were grateful for a friend's suggestion that we spread a coating of petroleum jelly on the front of the car to make it easier to flush the bugs off with water. I felt a little foolish but I did it. In a small town in Georgia, we pulled into a service station and asked the attendant to check the oil. He tried to lift the hood, but his hands kept slipping. "What ya got on your car, mister?" he called out. "Vaseline," I said. Before I could explain further, he responded, "Whatza matter? Ya got a tight garage?"
