Dirty Cars and Wax

I was wondering if there is a way for mechanic shops or other shops to sell car wax or something akin to that.

To perhaps extend the time it takes for a car to get dirty. Having to clean / wash a car every 10 minutes or so after driving makes me sad and I think having something else available to help clean and then wax to keep it clean and shiny longer. =^.^= Thanks for your consideration.
