Wondering what the deal is with the 845 on our white durango. I applied a fresh coat a few weeks ago because I had some major issues removing some road grime on the lower portion of the sides. Two weeks later I proceed with my normal maintenance wash with ONR and I ended up having to use some Bug Squash at 3:1 to get the grime off. It wasn't nearly as bad as the previous time, but should I need to be using some sort of extra removal method. Does that paint just not like 845? On my other vehicles, I do not have to do this and they are maintained in the same manner. The grime just comes right off. Was thinking of trying something else on it.
