I live where they salt the roads and live on a gravel road so will definitely be applying the clear bra type protection as well as some undercoat. I agree that the undercoat will also act as a cushion in addition to a protection layer.

There are weeks where I might go a hundred miles or more on gravel for work, EASY. With the old Geos I don't worry too much about chips and all but I wouldn't want to tear up a new car.
