OP: I have a question that deals with a lot of what is being discussed in this thread, so I hope you don't mind me piggybacking on your question.
I live in Alaska, and the winters here are looooong. Unfortunately I have to live in the city, and we go through a lot of snow freeze/thaw cycles that usually result in wet, dirty, grime ridden roads for days.
After driving for a couple days in harsh weather my vehicle is understandably dirty. My only option (I live in a condo) is to go to a touch-less car wash and than use ONR to get what the car wash missed. Unfortunately I generally find (even after using the ONR) that there is still a lot of surface contamination that I am only able to get off with hard scrubbing (which I don't do) or to clay the surface. Even after using the ONR I am only able to blot the water off. I think if I were to wipe it off it would scratch it up pretty quick.
I just detailed the truck with DG 601 and 105. Is there anything more that I can do to keep the grime from sticking to the truck? It's almost like a glue after I've driven for a couple days in the dirt laden streets.
