I use it to clean the bugs off the front and hit the black streaks after arriving. Bugs are best taken care of as soon as you can get to them. I've heard that many bugs contain an acid chemical that make them stick harder the longer they're on.
Really high-end paint manufacturers will tell you to stay away from anything with petroleum. Be careful about all the recommended home brews. Dish washing detergent and general purpose spray cleaners are cheap solutions that can wear away the surface film or produce micro-scratching. Generally, you get what you pay for. If I'm going to pay a lot for my camper, I'm sure not going to go "cheap" on a cleaner. Happy camping.
