I've read every post in this thread and I wanted to ask you something that I did not really see addressed.
I have a 2006 330i which I keep impeccably clean. But living in Germany and reaching 120 mph and higher I have a real problem with bugs. I've tried bug remover (Turtle wax) and spend way too much time trying to high pressure wash the bugs off (which I know is not the best for the paint). I've considered a clear bra but I like the challenge.
What is the best method to remove these bugs? This just drives me absolutely nuts. I just ordered some Mother's Clay although I'm still a "clay virgin." Will that help? Anyway TIA for any help you can provide.
