It worked! (best used in combination  ) I ran both mine and the wife's car through the car wash yesterday, I even left the car windows open. OK I'm not that weird,…. it was late and my wife reminded me that my car windows were open and I'd better close them in case it rains. I said “If i close them it won't rain tonight!”. So I didn't! So the back seats are a little wet, so what, its worth it! 

Well what do you know, its raining! so far just about 0.14 of an inch! Nice slow steady rain since about 5:30am.
