Its irrelevent because like i said you put it on WHILST washing the car so theres going to be water marks on the car through washing it anyway. I dont know i might be different from everyone else but i tend to clean th whole car not just remove the bugs.
So when you use this miricle miguires stuff is it before or after washig the car. The reason i ask is because if you use it before washing there is going to be water mark after you have finished anyway, if you apply it after washing then whats the point cause you might as well of used my method and saved time and effort and got rid of the bugs whilst washing it
