The active effort to remove road grime and these road films every time you accumulate them is honestly a bit pointless for me, even for us who detail cars, we don't usually bother that much with our cars with road grime, why? because you could get a thick layer of road grime even if it doesn't rain. If its rains however the water helps to act as a medium from the road and smoke to the paint thats why raining can really increase the amount of road grime on the paint, but even if its not raining, try following a bus for some time, or try to travel through Edsa for 4 hours, you should already collect enough road grime turn your applicator pad grey thats why we usually don't bother with it anymore just as long as its not gritty
