After I wash my truck it's time to wash it again. By the time I'm done wshing it and drying it, pollen and dust is all over it. It's very frustrating. I use the California duster a lot. Last week, I had just finished drying it and a bird flew over and basically crapped all over the passenger side. This bird had to be storing crap for a week!!! I had to re- wash the entire passenger side and roof.
