I past a few Council gritting lorries today in and around Bristol which means salt on the road and lots of potential rust.... so I won't be using any of my kit cars again until it clears and after a good rainstorm.
I am surprised at how many people are not aware that road salt rots their cars. But then, would the council say "Yes we can keep the road ice free but in the process we will take years off the life of your car" ::)
